Period Problems

I’m 16. Have a steady boyfriend of over a year now. Been bleeding for a long time, since two days before Christmas. Sexually active, don’t have any STD’s and not pregnant. (I took a test a few weeks back and thought it was positive but then the next one was negative) I’m so sick and tired of this but 1: can’t talk to my parents about anything 2: don’t have any money to go to a doctor 3: don’t know how to even make an appointment 4: my boyfriend wants to help but doesn’t know how

Honestly if you have any advice that’s great but if anything I would just like to know I’m not alone in being scared and having no way to help myself 😢 thanks lovelies
