So I have a question..

I want to go to OB/GYN and start on taking birth control because it has become really difficult to predict my period. For example, I almost went the entire summer without a period(May 10, didn't get another one until Aug 9) last year. Then I had a cycle of 29 days a few months later.

The problem is, I don't know how to talk to my mom about it. Not that I am scared of asking, but the fact that she's so dismissive about medical topics and especially personal problems that I have. I am sexually active, but I can't tell her that because of the fact she can't handle it, she's literally asked someone else to ask me if I had sex.

What should I even do? I really need to go see a gynecologist, but I am scared that my mom will just blow me off
