Cervical cancer anxiety

Hey all, I'm not sure what I'm hoping to get from this but I'm just really worried and don't know what to do or who to turn too..

4 months ago I had my 3rd boy and I've been bleeding ever since, seen the doctors had blood tests, speculums a TVS and no one is telling me anything! I keep asking what could be causing it so I (maybe a bad idea) did my own research since the doctor told me I have an irregularity with my cervix, since the the gynaecologist said she could see an abrasion so sent me for a TV's after doing a smear test and checking for left behind placenta, nothing she could find.

2 hours after my smear and the TV's I've had really bad cramps and straight after the scan I had bright red bleeding when I asked if it was normal he just said sometimes!

I'm going out of my mind worrying what this could be, everything I find points to cancer and I have really bad anxiety so I know I shouldn't be researching but I can't stand all this waiting
