The pill.

Okay, I need some opinions. Me and my boyfriend had unprotected sex this weekend And he came inside of me. He knows how I feel about having kids.(I really want kids at a young age instead of being in my mid/high 20's) and we talked about getting the pill when he came inside of me. But it was a suggestion. He got it today and He wanted me to take it (i did) but I feel kinda sad and upset that he got it and that I did. Am I wrong for being upset or??
