1st trimester ends roughly 13.5 weeks… 2nd trimester ends at roughly 27 weeks…and then you’re in your 3rd trimester. 40 weeks broken evenly between the 3 trimesters is roughly 13 1/2 weeks give or take a day or so

It might be because a child can survive now at 24/25 weeks.

My son is 2 and it was 28 weeks, according to my doctor. HAS to be a typo or something? Lol

This confused me so much when I was pregnant. Every book and website I read said week 28 was the start. Lady at WIC argued with me saying I was in the 3rd trimester at week 25. I was like no I still have 3 weeks
