I guess I have not clearly understood exactly "how you get pregnant" . YES I KNOW YOU HAVE SEX AND HE CUMS AND THEN IF THE EGG AMD SPERM MEET but do you have to be ovulating to get pregnant is my question? You see tv shows like 16 and pregnant and the girls always say things like "it was just one time" or "I didn't think I would get pregnant" so are they just lucky to get pregnant on accident??
