I had oral sex with my boyfriend, and now Im noticing brown discharge from my vagina, which is worse in the mornings. Ive also been urinating more frequently. My period was due two days ago, but I still havent gotten it. I took a pregnancy test, and it was negative. The date of sex was 26th February, and I tested today. Could this be something else?

Since your pregnancy tests are negative, it is less likely to be related to pregnancy. I recommend you to consult a doctor for a proper diagnosis and treatment plan. You may need a pelvic examination and some tests to determine the cause of your symptoms. In the meantime, you can try using over-the-counter antifungal medication like Clotrimazole (such as Canesten) for possible yeast infection.
