omg girl 4 months is soooo little time!
DO NOT! u will regret it! i gave it up to my ex bf for our 1 year anniversary and we broke up about a month later not for the fact that he wanted to hit and quit it, i broke up with him beacause i wanted a child, i regret it sooo bad now, i thank god i didnt get pregnant but just think about it okay
you might regret it later
get on birth control, im not on it but i talked to my mom about it and she said she didnt want me on it for some strange reason but use condoms, they are 99.9% effective, also check the expiration date on them and DO BIRTH CONTROL!
if any other questions pm me
