when is 9 months pregnant

Being "9 months pregnant" typically means you are around 36 weeks into your pregnancy. The ninth month of pregnancy can start between weeks 33 and 36 and ends when you deliver your baby, usually around 40 weeks. Pregnancy is generally counted as lasting about 40 weeks from the first day of the last menstrual period (LMP), so "9 months pregnant" is a common way to describe being in the final month or stage of pregnancy, close to full term and delivery. It is important to note that months in pregnancy don't exactly match calendar months since pregnancy is counted in weeks. Many sources agree that 36 weeks correspond to about 9 calendar months of pregnancy. Labor and delivery usually occur around 40 weeks, but births can naturally happen between 37 and 42 weeks. So, when someone says they are 9 months pregnant, it normally means they are nearing the end of the pregnancy, typically between 36 and 40 weeks pregnant.
