My mom was pregnant and didn't know it she said she got her period every month. She was walking one day and she passed out in the street and people called the ambulance she was taken to the hospital and they told her she was 5 months pregnant. A month later she gave birth to a 6mth premature baby girl.

Thankfully my sister is all grown up.

I have a question can that happen to me? Can I get pregnant and not know?
