Yesterday i had sexual intercourse. Penetration hurted at first but then it was ok. We had protected sex, but a little bit of semen eas out. Immediately ee bought the plan B pill and everything was good. Today in the morning everything was normal but like at 3:00pm my vigina started hurting so bad (inside) and when i pee it hurted even more. Pain persist even if not urinating and a little bit of blood or spotting appears. Is this a side effect of the pill or is a bladder or yeast infection . Oh and i have the urge to pee just after peeing
