About a week ago I started feeling very itchy in my vagina, when I had sexual intercourse it felt itchy and wasn't enjoyable. I went to the doctor and told her my symptoms, she said most likely it's a yeast infection due to the fact that I'm itchy and it burns in the beginning when I pee, she told me to buy monista, I bought the 3 day treatment. When I put it in it burns and irritates but it's not severe so I managed to take all 3 treatments. However, I notice that i am having a yellow/green discharge after using the product. Is this normal? Should I be worry ? I highly doubt I have a STD I've been with the same partner for years he has no symptoms or issues and about 4 months ago I did blood work and everything was negative.
