how do you know if your pregnat
If your stomach swells to the size of a beach ball and you have morning sickness and crave weird things to eat and if around 9 months about a gallon or two of water all of a sudden come out from between your legs and you feel like you are going to pass a bus from between legs and this little tiny crying naked person comes out. I think those are some really good signs that you were pregnant. Good luck
Its pregnant, and you wouldnt be asking if you didnt have unprotected sex at 13. Missing your next period is a good indication!
Take a pregnancy test, thats all I can say.
