January 7th i noticed that in my underwear i had dried up yellow discharge in my underwear. The next day i had unprotected sex with my boyfriend because im on birth control. That friday i began peeing frequently like every 15 minutes. (I did have some bloating but it was present for a day or two )I've had some burning here and there but not everytime i went to the bathroom. I also had some pressure on my bladder so I bought some cranberry juice and it seemed to help and the uncomfortable symptoms seem to subside. Although i noticed if i get really anxious and worried the sypmtoms seem to come back. Now my pelvic bone has some pressure on it currently. I do also have a lot of gas and my stomach hurts aswell. What could this be? Im trying not to worry and look up my symptoms but its really hard not to. Im only 18 years old i really hope i dont have any type of cancer :-(
