When does the 3rd trimester start?

Question

26 or 27 weeks? I feel like everything I read is different.  26 weeks today, 98 days to go! Baby boy is kicking up a storm at random times throughout the day. Kinda over being pregnant already though. Come on December where are you???

Answer

Since you are pregnant for approximately 280 days, each trimester has 93.33333 day. So the second trimester begins at day 186.66666 which is right before you turn 27 weeks.

Answer

Medically-the 3rd tri starts at 28 weeks.
