Sounds like a yeast infection/thrush. I used to get it quite often when I was on the pill but haven't had it since! (touch wood) Also friction from sex and rubbing can help candida thrive which causes thrush. and the brown blood is probably your lining shredding, thats something I'm currently trying to deal with but mine turns heavy and i had it for over 2 weeks! If you get something over the counter for your irritation get canesten duo pessary.. vagisil doesn't work.
Thank u since my monthly has stopped So has The itching and I am going to go to The Gyn anyway cause I do believe it maybe a yeast infection something I get often because of my pcos and my balances changing all The time
You probably have a yeast infection, but go to the doctor if you're unsure.
