Weird spotting for 4+ months now

Hey Ladies,

Been having the odd spotting between my cycles since August 2020. It slowly started off as pink spot not enough to smear my underwear but it’s there when I wipe. now Jan 2021 what started off as two day pinkish mid-cycle spotting slowly progressed to dark brown blood with spotting it also happens regularly 2 weeks after my period ends. It’s super weird. I had my endovaginal ultrasound and pap done recently earlier this month. Turned out be completely normal. Any of you has experienced this?. Sex drive is next to nil!, that sucks so..
