How come pregnancy is 9 months but 40 weeks?

That’s because months vary in days. Averaging 365 days over 12 months, your average month lasts 30 days and 10 hours. So 280 days (or 40 weeks) is actually nine months plus nearly a week.

Can a baby stay in the womb for more than 40 weeks?

Most pregnancies last 37 to 42 weeks, but some take longer. If your pregnancy lasts more than 42 weeks, it is called post-term (past due). This happens in a small number of pregnancies. While there are some risks in a post-term pregnancy, most post-term babies are born healthy.
