How to Estimate Your Conception Date

There are a few ways to estimate your conception date: you can approximate based off the dates of your last menstrual period, or you can schedule a free limited obstetric ultrasound to estimate your baby’s gestational age.

Menstrual Cycle

To estimate your conception date based on your menstrual cycle, simply add approximately two weeks from the first day of the last menstrual period you had before you became pregnant. This should give you the start of your ovulation period, when your body is most fertile and likely to become pregnant. Ovulation is a normal part of a woman’s monthly cycle, and it usually happens about two weeks after your menstrual period ends.

Keep in mind that this method isn’t 100% accurate. It is possible to become pregnant at any time during the month, not just during your ovulation period. You can even become pregnant during your menstrual period. Also, remember that these estimates are based on the average woman’s regular 28-day menstrual cycle. If your cycles are irregular, this method may not work for you.

You should also know that a man’s sperm can stay alive inside your uterus and fallopian tubes for several days after intercourse. In other words, you might not actually conceive until days after having intercourse.

Limited Obstetric Ultrasound

In contrast to menstrual cycle estimation, limited obstetric ultrasounds are much more accurate at estimating your conception date. This is because an ultrasound can directly observe your baby’s development and estimate its age. Ultrasounds can also determine whether your pregnancy is healthy and viable.

We offer free limited obstetric ultrasounds at our clinic. An ultrasound can help you determine when you conceived and when you are due, allowing you to consider your pregnancy options more accurately.

What If I Don’t Know the Date of My Last Period?

If you aren’t sure when your last period was, or your periods are not very regular, it will be harder to determine your conception date and due date using a pregnancy calculator. Your best option in this case is to get a free pregnancy ultrasound to see how far along your pregnancy is, along with an estimate of your conception and due dates.
