Birth control

Ba

This guy and I have been talking for a while( I am 13 he is 14) the other day we were talking about having sex and I told him no he asked why I told it was because I am not on birth control, I told my mom and we talked about it again and told me if she put me on it it was not the green light and I know. She just doesn’t know what would be safe for me. If you have any ideas please let me know.
