Period won’t stop

Rebecca

I’m not even sure if I can call this a period, but for 10 days now I’ve had light flow of dark brown bleeding with stringy brown discharge. Usually my periods are 4 maybe 5 days max. I’m getting really worried and my GYN hasn’t called back. Negative pregnancy test. Been TTC since December 2020. 1 MMC in late April. Has this happened to anyone before though? Should I be worried? I get SO worked up about this stuff because I want a baby so bad and I just want things to be okay so that can happen.
