Doctors count from the first day of your last period, LMC, as the first day of your pregnancy. In reality you typically will ovulate and become pregnant about 10-16 days after that. They also take into matter the length of your cycle, how long between periods. That's why 2 weeks early or 2 weeks late is considered normal for the prenatal period. As every woman ovulates on a different day of her cycle. A 12 week ultrasound will likely pinpoint how far along you are as most babies grow at the same rate for the first 3 months.

Can you count back the weeks of your pregnancy from a dating scan to see when you may have conceived if your LMP is unknown?

I just had a child and I had no idea when my last MP was or when around he was conceived, but if you know already how old around the fetus is, then you can get somewhat of an idea, but it won't be exact. Yes. If you count back two weeks less than the length of your pregnancy, that is approximately when you conceived. For example if your dating scan says you are 10 weeks pregnant, counting back 8 weeks will give you your approximate date of conception.
