Why would you be taking birth control if you're pregnant anyway? If you did it would mess things up a little bit concidering all it does is boast hormones.

No I meant in the long term, like say.. I take birthcontrol right will it affect my reproductive system later if I want to have a baby??

Oh right...Haha. Yeah I guess I should have realized that

To answer the question, no it won't have lasting effects on your reproductive system.
