I won’t stop spotting

And I’m getting annoyed. It was bad enough to have my period show up two weeks early but now it won’t end and I’m kinda worried.

I experienced an extended period in 2018 that lasted almost two months and the only way to stop it was going to planned parenthood and being prescribed birth control...but that’s off the table now bc I’m TTC.

I have a doctor appointment next week but I’m impatient and nervous. Anyone ever experience something like this?
