How Does a Conception Calculator Work and Why Does It Matter

You recently found out that you are a few weeks pregnant, but you’re now wondering exactly when your baby was conceived. You can find out using a conception calculator. There are many free websites available where you just enter your due date and some additional questions. The calculator will figure out the possible days you might have conceived your child.

The conception calculator assesses the date based on your biological cycle. Conception occurs when the sperm and egg unite and implants itself in the uterus. During each month, there are a few days where the body is susceptible to getting pregnant. Typically, the body ovulates 14 days before your expected period and one can become pregnant if one encounters in sexual activities up to 5 days before ovulation.

Most women have 28-day cycles, which assumes that they ovulate on day 14. However, some women with longer cycles ovulate after day 14 and their baby’s expected due date will be postponed.

It’s important to remember that sperm can remain in the women’s reproductive tract up to 5 days after sexual intercourse.

Women may want to use the conception calculator for different reasons. For example, if a woman had unprotected sex with more than one partner, she can use the conception calculator to figure out who the father is. In cases where there was no period between the two encounters, the woman will have to use a paternity test to figure out who the father of the child is.

It is hard to track down the exact date of conception unless the individual carefully tracks her cycle or has had intercourse only once during that cycle.

Some women notice that their conception date is different when calculated using an ultrasound versus a conception calculator.

The conception calculator is used on the first day of the last menstrual cycle to estimate the date of conception. On the other hand, ultrasounds use the size of the fetus to calculate its gestational age. The estimated date can often change when the prediction is made using an ultrasound because the fetus size is always changing.

The conception date based on a conception calculator will always be the same.

If you would like you calculate your own date, use the following methods below

1. Determine when you had your last menstrual cycle. This helps you estimate the time of ovulation

2. Add 14 days to start of your last menstrual period. Women usually ovulate 14 after their period. This is the time period that the conception most likely occurred.

3. Use “Naegele’s rule” to double check. This rule is usually used to figure out the expected due date (EDD). If you know your due date and use the rule backwards, you can check your conception date. Subtract one year from your expected due date, add three months, and subtract 7 days to the first day of your last period.

Here’s what else you need to know about a conception calculator: most of them will generate a result based on average numbers and they can only be used as an estimation of when your baby was conceived.
