Question How Do You Moms And Your Doctors Judge Trimesters? I Have 4 Different Pregnancy Apps And Two Tell Me I Just Started My Third Trimester And The Others Say It's Not Til I'm 28 Weeks. I Am Now 26th Weeks 4 Days.
I was always taught that it's 28 weeks for 3rd trimester, but it could depend on how they are calculating it. if it's point of conception it's 28 but if they're calculating from last period that might explain the 26 week discrepancy.
