How to find out when a child was conceived. How to determine the day of conception of a child
The conception calculator is a simple program that will be useful to all women without exception: very young girls with an unestablished menstrual cycle, those who are planning or, on the contrary, want to avoid pregnancy, as well as expectant mothers. Let's take a closer look at situations in which a conception calculator would come in handy.
Monitoring the menstrual cycle. Gynecologists never tire of repeating that every woman should keep a calendar and accurately mark the dates of menstruation in it. Firstly, this is necessary in order to notice any deviations in reproductive health in time (shortening or, conversely, lengthening the cycle does not mean anything good). Secondly, understand in time that pregnancy may have occurred. This is important for those who long to become parents and for their “opposites.”
The Baby Conception Calculator helps you calculate your ovulation by entering the correct average length of your cycle and the first day of your last menstrual period. In addition to ovulation, the program tells you which days are also potentially favorable for conception. It is then that you need to “try especially hard.” For those who do not yet want to have children, it is better to avoid sexual intercourse on days marked in orange and green. Although, it is not at all a fact that this will help avoid pregnancy. The calendar method of birth control has long been called ineffective. So, it is better to use the online conception calculator for less responsible, so to speak, purposes and in conjunction with other means.
You can more reliably determine ovulation using two methods at once: for example, the calendar method and measuring basal temperature. And even simpler and more reliable are ovulation tests. On the days that our child conception calculator has highlighted in green and orange, tests should be done. But first, read the instructions carefully. It is similar to conventional pregnancy tests, but there are still some differences. As, for example, ovulation tests at the most likely time for conception are best done 2 times a day - morning and evening, so as not to miss the right moment.
The day of conception calculator will also serve well for expectant mothers who want to know the most accurate date of birth. Pregnancy lasts about 280 days. So, you can safely add 280 to the day highlighted in orange and you will get the approximate due date. Why approximate? The fact is that the duration of bearing a child depends on many factors. For example, a woman may give birth prematurely due to the characteristics of the cervix, or the amniotic fluid may break prematurely. Also, doctors can, for medical reasons, induce labor a little earlier. There are different situations.
Knowing the day of conception, you can set yourself the exact date of pregnancy. It will be approximately 2 weeks shorter than what the doctors estimate. The fact is that gynecologists calculate the obstetric gestational age, and for this you do not need an online conception calculator. You just need to know the first day of the last menstruation, it becomes the first day of the obstetric period of pregnancy. But sometimes you need to know the gestational age quite accurately, for example, when the doctor begins to suspect a post-term pregnancy, or if in the early stages the uterus is too large in size or, on the contrary, small. In general, in order to identify a possible pathology, you need to know the approximate day of conception. But who is watching this? Now all that remains is to calculate the conception calculator.
Even for those who don’t bother much with questions about how to get pregnant quickly, but are already planning parenthood in the very near future, our calendar will also come in handy. The fact is that the baby’s body, or rather all its organs, are formed in the very first days and weeks after the implantation of the egg into the wall of the uterus. And it is during this period, while there is no placenta, that the baby is most susceptible to any negative influences. Smoking, drinking alcohol, certain medications, etc. can lead to miscarriage or serious pathologies of fetal development. And the fertilization days calculator will clearly show you approximately from what time you need to “come to your senses” (if you haven’t done this before) and will remind you about the delay in menstruation.
A conception calendar is a convenient thing that allows a woman to monitor her menstrual cycle, namely, to determine dangerous and safe days in terms of a possible pregnancy. The child's conception calendar is a form in which you need to enter the first day of the last menstruation, and the program, using different colors, shows which days are the most “fruitful”. Try it, calculating the conception calendar is really very simple!
To better understand how the program works, we will present the main factors that were taken into account when creating it.
1. For the vast majority of women, ovulation (the only day in the month when the egg is ready for fertilization) occurs approximately in the middle of the cycle. Look at the conception calendar - the day of ovulation (exactly the middle of the menstrual cycle), as well as a few days before and after it are highlighted in orange and green.
2. Fertilization of the egg cannot occur during menstruation, or at the very end of the cycle. These “safe” days are represented in pink (see the baby conception calendar).
You can also check the accuracy of the data obtained by monitoring your condition during the ovulation period.
1. The amount of vaginal discharge will noticeably increase.
2. Libido (sex drive) will increase.
3. You may notice a jump in basal temperature (measured in the rectum), but only if you plotted it in advance.
4. An ovulation test (can be purchased at almost any pharmacy) shows a positive result.
5. Short-term, aching pain in the area of the uterus and ovaries may appear.
6. Using an ultrasound examination, the doctor identifies signs that an egg has been released from the ovary.
You can calculate your conception calendar right now! Enter the exact data about the beginning of critical days (the exact date) and in a couple of seconds you will receive the necessary information. Please note that the data obtained cannot be trusted 100%; nevertheless, our body is a big mystery, and any “little things”, such as stress or a change of place of residence, can affect the processes in it.
Note also that ovulation does not occur every cycle. Every woman of reproductive age has at least 2 cycles per year that are “sterile.”
Menstrual cycle
There is a common misconception that a woman's menstrual cycle should last exactly 28 days, and ovulation should occur exactly “on the 14th day of the cycle” or “in the middle of the menstrual cycle.” This is not true.
In reality, the menstrual cycle is divided into two phases - follicular (before ovulation) and luteal (after ovulation).
Follicular phase
The follicular phase (preceding ovulation) begins on the first day of the last menstruation and lasts until one dominant follicle (or several) matures in the ovaries. It ends with ovulation.
Luteal phase
The luteal phase (corpus luteum phase) begins from the moment of ovulation and lasts about 12-16 days.
In place of the ovulated follicle, a corpus luteum forms within a few days after ovulation. Its main function is the synthesis of progesterone and estrogens to maintain future pregnancy. If pregnancy does not occur, then after 10-12 days the corpus luteum undergoes reverse development, which leads to a drop in hormone levels, after which the next menstruation begins. If pregnancy has occurred, the corpus luteum continues to function and support the pregnancy.
In the absence of pregnancy, progesterone levels reach their maximum value about a week after ovulation - at this time it is recommended to take a blood test for progesterone to assess the function of the corpus luteum.
Duration of the menstrual cycle
The follicular phase can vary in duration (both among different women, and within one woman throughout her life). Typically, the length of this particular phase of the cycle determines the length of the entire menstrual cycle and affects the delay of menstruation - for example, if the maturation of the follicle occurs faster or slower than usual, or does not occur at all. The luteal phase usually has a constant duration (12 to 16 days).
Gender of the child
The sex of the unborn child does not depend on the location of the stars in the sky, the menu of the future parents, or the position at conception. The sex of the child depends on which type of sperm fertilizes the egg - those carrying a male Y chromosome or a female X chromosome. Spermatozoa of the “male” sex, as a rule, move more easily and more quickly than “female” ones, but are more sensitive to external conditions and adverse influences. Female sperm, on the contrary, are less mobile, but more resilient. Thus, if sexual intercourse occurs on the day of ovulation or later, the likelihood of having a boy increases, and if sexual intercourse occurs long before ovulation, then the likelihood of having a girl increases and the likelihood of conception decreases. However, experts believe that the reliability of this method does not exceed 60%.
Use our EDA (estimated due date) calculator to calculate the estimated date of birth of your baby. The calculation can be made by the date of conception, or by the date of the last menstruation. Select the appropriate option and enter the original date. As a result of the calculation, you will receive the cherished date, as well as an accurate pregnancy calendar with comprehensive information about fetal development and medical indications for each week. The calculation results can be saved by email or printed.

Yana asks:
Hello! Please help me determine the date of conception. My last period was on 02/21/2012. The cycle is approximately 27-28 days. Menstruation usually lasts three days. On the last day of menstruation (they had already ended by this time) on February 23, I had a condom, as far as I know, it didn’t seem to break. But I’m still worried. In the first days of March I had daily unprotected sex with a regular partner. Moreover, several times the sperm got into the vagina. 05/23/2012 there was an ultrasound. CTR of the fetus 71 mm, BPR 21 mm, OG 82, OB 65, which corresponds to 13 obstetric weeks, as far as I know. If with accuracy up to days, then 13 and 2 days. Second ultrasound 07/25/2012. BDP 52 mm, OG 187, OB 161. Help me figure it out, it’s very important to find out the exact date of conception. Could I get pregnant after sex on 02/23/2012??? Thank you very much in advance for your answer.
Yana comments:
Thank you very much for your answer and for the very useful links! I want to clarify the latter with you. There is a lot of information on the Internet about early ovulation, tenacious sperm, etc. Could sperm survive until ovulation? (If, of course, they got into the vagina during sex with a condom).
Marina asks:

Marina asks:
Hello. Please tell me. My last period was 07/14-07/18. The cycle was 28-30 days. I went for an ultrasound on 08/26. The pregnancy was stated at 5-6 weeks.
Can you find out at least the approximate day of conception? I just calculated that 6 weeks fall on July 14. Now I don’t understand when I could get pregnant, or I’m counting incorrectly.
In your menstrual cycle, the probability of pregnancy falls on July 25-31. As a rule, the period is set obstetrically, that is, from the first day of the last menstruation, and not from the date of conception.

Lydia asks:
good afternoon, tell me, is it possible to find out the exact date of conception, this is very important, menstruation should come on August 17, sexual intercourse was on August 2 and July 28, August 2 is just one of the days of ovulation, the test showed positive, I went for an ultrasound, they said it was early What else should I do if pregnancy occurs, on which of these days? Thank you in advance
Please indicate the average duration of your menstrual cycle and the date of the start of your last menstruation, which will allow us to calculate the ovulation phase and, accordingly, the days of expected conception. I also recommend that you take a blood test for hCG after 7-10 days, which allows you to diagnose pregnancy in the early stages. This study can be carried out no earlier than 7-10 days after the day of possible conception.

Lydia asks:
last menstruation from 12/07 gj 17 average cycle 39 days using phone app ovulation from July 29 to August 4
help, it’s important to find out on which day conception occurred, if it happened on August 2 or July 28
In your menstrual cycle, the ovulation phase falls on July 25 - August 2, so conception could occur on August 2 or July 28. Unfortunately, given the short interval between sexual intercourse and the fact that both of them occur during the ovulation phase, there is no way to determine on which day conception occurred.
