Second Trimester: 14 and 0/7 weeksâ27 and 6/7 weeks (Months 4 â7) Starts at the beginning of the 14th week after your LMP and lasts through the 27th week of pregnancy. Third Trimester: 28 and 0/7 weeksâ 40 and 6/7 weeks (Months 7â9) Starts at the beginning of the 28th week after your LMP and ends with labor.
