Things to know:

Im 16, hes 17

Weve been dating for almost 4 months

Weve had sex multiple times(with condoms none have broken)

No our parents dont know

....

Yesterday I went to my boyfriends house and he decided to take a nap. His mom called me into her room and told me she wanted to speak with me privately. She said she knows me and him havent been "messing around" but she wants me on birth control. She also said that shes not saying that its okay for us to have sex and that she would rather us wait but she knows that accidents happen and she just doesnt want us to end up with a baby right now. She told me she was going to talk to my mom about it. Then today she asked my boyfriend before she dropped him off if he had condoms with him and he said no and she said you need to go buy some.

What kind of birth control would be best for me to get right now?

Im also wondering how it will effect me?
