I went to go get that embarrassing check up in order to get birth control, but i never got them..my friend gave me two months worth of samples just to see how i liked them and they made my head hurt alot..now i'm taking my other friends birth control pills which i only have 3 weeks left in that pack..so i heard that if you take different birth control pills you can mess up your system and may cause you not to be able to have kids..do you guys think that what i have done so far could affect me..i'm really worried about this..the reason why i'm doing this is because i don't want my mom finding out that i'm sexually active..but i don't want to mess up myself and not be able to have kids when i want them..do you think i'm ok?..i really need some advice on this one!!
