im 18 and i have a fiancee who i love dearly and worries about the chances of me getting pregnant i get my period every couple months i might get it back to back every once in a while but most of the time it may be every two months sometimes i'll go three ! i've heard it may just take a little longer and it may be more challenging. at first we thought hey we'll have fun trying but now we're thinking that i might need more help and i dont want to take birth control pills. ( btw we havent had sex he wants to wait but we're planning ahead and things arent looking so good i know he wants to have a kid of our own and i do too ) :$
