Weird period lately 😦

So i have been having weird periods for the past months. I had an itch for over 1 year were i was treated with everything and wouldnt go away, on january my obg gabe me a rx for clyndesse and gynazole 2 creams to use vaginally. 3 wks later the itch stoped but than again i also stopped bathing with oil of olay and stoped using softener in the clothe so wouldnt say what cured the itch. Since than i do not get red periods but only black like charcoal looking, along with chunks of skin and cream. And while having sex thes chunks of cream and dark skin that looks like dirt comes out, here is a picture. Sorry if it gorses you. My obg says is perfectly normal cause thats just the birth control. HAS THI HAPPEN TO ANYONE. IM SCARED. Oooh and i spot in between periods for like 2 or 3 days.
