Period for 3 months!!

I'm currently (still 😫) on my period, and have been since January 13. I have a problem with my periods, for the past year and half, I got my periods every 6, 5.5, and 4 months. The first 2 were late, but still regular 7 day period. After the 4 month period, however, I've had it. I've gone through so many packs of pads, my periods have always been heavy, since I first got it at age 10 and I'm constantly wearing overnight extra long pads. A new thing is this period cycle, the blood is dark brown for a week then dark red, then red, then dark brown again. Before it was just red. My clots are small and hard balls most of the time. I have lots of pain one week, then nothing for two, and even worse pain for a week, and it continues. My last visit to the gynecologist was during the 6 month frame, I went when it was still 5 months, and he said I had immature HPO axis, which is when my womanly organs haven't quite developed yet. but that was nearly 2 years ago. I had another appointment with him, but cancelled due to covid 19. I have some health problems: nighttime bed-wetting, since I was 8; a bit overweight, chronic migraines, short Achilles tendon (prob not related but..), and as mentioned before immature HPA axis. Me and mom thought I had PCOS, because she had it but the tests said I didn't. I'm still very hairy though. I'm only 14, help.
