I’m scared! Please help 🙏🏻 TMI

Sorry for the TMI in advance. 🙏🏻

So Idk if this is even the right group but I had my Pap smear on Friday. Sunday I had light spotting. Overnight it got heavier and it’s bright red. I’m 9 days until my period is due and I’m worried this is abnormal. I’m cramping and have bad lower back pain.😓 I think it’s too much for implantation bleeding. Doctor has no availability today. Should I be concerned. I had abnormal pap and colposcopy done in 6/2022. Has anyone had this happened?!?!
