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. Most expectant mothers don’t realize that both menstrual and ovulation periods count as the first two weeks of pregnancy. While it’s true that most pregnancies last 40 weeks, there are other factors at play which will determine your due date. Schedule an ultrasound appointment with our nurse today. This method is much more accurate than date-based calculation. Pregnancy ultrasounds look directly at the development of your growing baby to determine its age and when you likely conceived. This is why a pregnancy confirmation ultrasound is the best way to know how far along your pregnancy is and to determine when you conceived.
All of these factors can make it hard to know when exactly you conceived. Conception is a process and takes time, and a man’s sperm can actually stay alive inside your body for up to a week after sex. You can also simply try to determine the last time you had sexual intercourse, but this method isn’t totally accurate either. In other words, calculating conception based just on your body cycles can be difficult. Some women simply aren’t sure when their last period was. Others have ovulation periods closer to or further from their menstrual period. Some women’s menstrual cycles are irregular. However, not all women have the same cycles of menstruation and ovulation. Ovulation usually occurs about two weeks after your menstrual period and lasts for two or three days. But if you're impatient to know when your baby will arrive, then our pregnancy calculator tool gives you an estimate due date without the wait.In general, women can only conceive when they are ovulating – that is, when their ovaries release a new egg into their fallopian tubes for fertilization.
