When does the second trimester start?

Question

Answer

My doctor told me 14 weeks and BabyGaga tells me 14 weeks as well. This is what I go by

Answer

I like to believe that its starts at 13wks...here's why... We are preggers for 9 months. Every 3 months is a nxt trimester, thats why it begins with "Tri" 
It just makes it much easier for me.

Answer

I'm going by 14 weeks because I'm still throwing up in week 13...keep hoping week 14 is better :)

Answer

13 weeks 3 days. If you're technical. My doctor said hearing a strong heartbeat at 12 weeks is when she considers you in the second trimester.

Answer

To me, it's the end of week 12, so the beginning of week 13 ☺

Answer

Google it or ask your OBGYN, the 13th week is the first week of the second trimester

Answer

My midwife says week 13

Answer

I go by 14 weeks

Answer

The What to Expect When Expecting book puts 14 weeks as the start of second trimester.

Answer

I say say start of 13th week. If you divide 40 by 3 you get 13.333 so thats why different people go by different weeks. Because technically its 13 weeks and a few days. And then third trimester starts week 27
