Birth control??🤨

I’m 15 and have a boyfriend that really wants me on BC. Which I can understand because although we use protection accidents happen and it is very stressful to say the least. I don’t have the best relationship with my mom so I have no idea how I would go about asking her, I’ve never been to a gynecologist and am not really fond of someone looking down there because I hate regular doctors. I don’t like the idea of getting something inserted in me anywhere and absolutely hate shots, so I feel like maybe the pill is the way to go? But a lot of people have said they gained weight or their acne got worse while they were on it. I already struggle with both weight and acne so if that’s the case I won’t even consider the pill. Any suggestions or experiences with the pill or telling my mom?? Thanks!
