In humans, how long does a normal pregnancy last on average?

I had a premature baby. He was born at 27 weeks. He was kept in an incubator for 6 weeks and we brought him home. He is now 33 years old and fit and healthy. He has no health issues. I am blessed.

Sarah, I agree, and 40 weeks is 10 months and that's what doctors will tell you is technically you are pregnant for 10 months not 9 mo...

Human pregnancy really is 10months. 9once she realizes she's pregnant.

I’ve always had to get my babies out early and scheduled them to come out early too. I’ve had 3 babies and all was c sections.
