Omg I smelled an fool, birth control is not 100% safe but hey its better than nothing, my advice stop having sex!!
Who cares if your 13 if your not old enough to use b/c or deal with the fact you may be pregnant then $hut the f*ck up and deal with it like we have or never have sex till your married so atleast some guy can respect you instead of him thinking of you as just a piece of grade .A meat.
I wouldnt be shocked to see you preggo by 15 its attitude like yours...
Btw do you really want your kid to be another welfare kid cause mommy couldnt finish school/speak or because you though sex was better than your possible childs welfare wake up and smell the coffee f*ck go to planned parent hood and tell them your too stupid to have sex you need b/c!
