Heavy bleeding after I'm supposed to ovulate?! Help!!!

Je

I'm confused and scared! I got AF on 8/16-8/20 and according to Glow I was supposed to ovulate on 8/30 but so far all my ovulation tests have come back negative for the past two months and now I started bleeding heavily yesterday on 9/3. Today 9/4 I'm still bleeding heavily with pelvic pain and cramping. I thought it might be ovulation bleeding but it's really heavy bright red and today I noticed some clots. I know TMI... so sorry. I've also been feeling really tired and dizzy with back pain. Has this happened to anyone before? Comments please!
