Even if you had sex only once during your six-day fertile period, you may not have actually conceived that day unless you happened to be ovulating. But figuring out an accurate due date based on conception date is easier said than done: Unless you were really deliberate about tracking your ovulation or were able to make a baby in one shot (and had no extracurricular fun with your man otherwise), knowing which day was the big one isn’t clear cut. If you happen to know the exact day you conceived, you could calculate your baby due date by counting 38 weeks from the date of conception (38 weeks is said to be the length of human gestation).

So when you’re using an online pregnancy due date calculator, please remember that online pregnancy calculators can only provide an estimate of your due date, and that a due date calculated by your healthcare provider is the best date to use. It is quite normal for a baby to arrive a week or two early or late. Remember though, that only about five per cent of babies arrive on their actual due date^.

If you have irregular cycles you can ask about a ‘dating scan’-an ultrasound done around the six-week mark which calculates the due date based on embryo size. This is how your pregnancy healthcare provider will calculate your due date. This means, that by the end of the third gestational week your baby will be one week old, but you’re already at the end of Week 3 of your pregnancy. So if you have a regular 28-day cycle you’ll ovulate around Day 14 and your baby will be conceived around that date, the start of gestational Week 3. Most pregnancies will last 40 weeks (38 weeks from the actual conception date).īasically, the start date of your pregnancy is actually the first day of your last period-Day 1 of your menstrual cycle. How is your due date calculated using this pregnancy calendar?ĭid you know that on the day your baby is conceived you are already two weeks pregnant?! It doesn’t sound right, but that’s how gestational weeks are calculated.
