Whats going on with my body?

Hello gals.

I was 3 days late for AF, couple days later i stopped bleeding, the next day bleeding for 4 days. Been off AF for 3 days, went to use the bathroom, realized there was some egg white discharge with light faint bleeding. I have PCOS and this happened last month, but I tested and it was negative. I've lost tons of weight, very fatigued, sore everywhere, can't sleep at night (which is weird even though I'm tired, lol). I get 2 hours of sleep then throughout the day, I'm very tired. I recently have noticed my BBT has gone up, every morning i wake up burning up and that started last month. Not sure what's going on. I've also been getting dizzy, really bad stomach acid and lightheadness. If I'm not constantly eating or drinking, I get super bad stomach acid. What is this? Please help!! This has never happened to me.
