![]() The best time to take a pregnancy test is about two weeks after your last period if you have a regular menstrual cycle, or at least 21 days after intercourse if you have an irregular cycle. In this case, you may want to wait until at least 21 days after you had intercourse to take a pregnancy test. However, if you have an irregular menstrual cycle, it may be more difficult to determine when to take a pregnancy test. This is because ovulation typically occurs about two weeks after the start of your last period, and it can take several days for the fertilized egg to implant in the uterus and for hCG levels to rise.

Luckily, our pregnancy due date calculator can help. Unless you can pinpoint exactly what point of your ovulation cycle you were in at the time of fertilization, it’s difficult to know how far along you are and what date you’ll meet your baby. That means that simply estimating nine months from the day you take a pregnancy test isn’t going to calculate your due date, and, even so, factoring in a few weeks here and there for ovulation won’t either. Many won’t be aware of their pregnancy until their first missed period, and by that time they could be up to five weeks in.
