I have been doing alot of research on this and keep getting conflicting dates! I am 11 weeks today (woohoo) and wondering what did you consider the first day of your second trimester to be? I’m adding a poll because, Hey, we all love polls right!

My Mayo Clinic book says the end of week 12/ beginning of week 13. That is what I am going with!

@PilotsGirl56: that is what baby center said also but ALL the other sites ive read said 13 weeks 1 day!
@traceyjoy: that is what I thought!

I went with 13 weeks. That’s when we had our first ultrasound and then announced the pregnancy.

Yes, the Mayo Clinic’s Guide to a Healthy Pregnancy (which is an awesome book, btw!) says 13 weeks. My doctor says 13 weeks, however 1/2 of the doctor’s you talk to you and sites you read online re: pregnancy will say that 14 weeks is the true beginning. Regardless, I started counting it at 13 weeks. 🙂

The My Pregnancy app by Babycenter says 14 weeks is the first week of the 2nd trimester.
