Pelvic Pain!!!

So I wrote about a bunch of problems I've had with my period about a month ago. (They're unbearable) I get hot and cold flashes extreme cramping and it makes me throw up etc. I was supposed to get a gyno appointment but it turns out no one really takes my insurance especially for someone my age (I'm 16) I kinda just have this feeling I have endometriosis or maybe I'm just paranoid and a hypochondriac. But recently I've been getting these pelvic pains and idk if that's normal or not. I also got them when my boyfriend and I had sex a couple of days ago. That was the only time it hurt the worst. I'm currently laying in bed and it's been giving me insomnia because it's been hurting for the past couple of days. (The pain is tolerable just uncomfortable) I haven't seen any changes in my cycle, I don't think I'm pregnant either I really haven't had any symptoms other than the pain and I'm not sure if I should tell my mom or not. I really need some advice please
