How Many Weeks Pregnant Am I?
Pregnancy is measured from the first day of your last period, not conception. At 6 weeks pregnant by LMP, the embryo is actually only 4 weeks old. Count the days from your LMP to today and divide by 7 to get your current week. At 40 weeks, you are full term.

Common questions about How Many Weeks Pregnant Am I?
What are the key milestone weeks in pregnancy?
Week 6-8: heartbeat detectable on ultrasound. Week 12: end of first trimester, miscarriage risk drops sharply. Week 20: anatomy scan. Week 24: viability milestone (babies born now have a survival chance). Week 37: early term. Week 39-40: full term. Week 42: post-term.
Is 8 weeks pregnant the same as 2 months?
Not exactly. 8 weeks by LMP dating equals about 2 calendar months. But pregnancy months and calendar months differ slightly - pregnancy is counted as 10 lunar months (4 weeks each), not 9 calendar months as commonly said.
Why does my doctor say I am 2 weeks ahead of when I think I conceived?
Doctors count from LMP, which is about 2 weeks before ovulation and conception. So at the moment of conception, you are already "2 weeks pregnant" by the medical counting method. This is standard obstetric dating used worldwide.
