So much regret...

I regret telling my mom I’m sexual active with my boyfriend. We’ve been together for over a year and both of us were ready and I’m trying to be mature about it and asked her to put me on the pill, I’m 16, 17 in 5 months and I feel that if your ready and if it’s your decision to do it it should be fine, she won’t let him up in my room and I’m so scared to bring him home because she’ll say something to him, if I could turn back time I would, and if I knew she wasn’t going to support or help me, I would of never if said it to her
