Why am I bleeding and having to pee a lot after sex?

So me and my friend did it last Friday. WITH protection. Latex condom. The day after that, everything was normal. But then the very next day, I masturbated and notice some blood so I stopped. Monday, during school, I suddenly have that feeling where I need to go to the restroom but I know that I'll still feel like going, even after peeing already. Ever get that? And when I wipe, I notice brownish blood on the toilet paper. It's been 2 days and I'm still noticing blood on the toilet paper & still experiencing that feeling of needing to go use the restroom 24/7. It is very uncomfortable. I am so scared I might be pregnant and It is hard to tell if I missed a period or not because I cannot keep track of my period. It's pretty much random. My friend told me maybe the condom was irritating my skin so I developed rash and when I masturbated, it must have scratched the rash or something. But I don't know. It sounded right because I never really use a condom in my past relationships which is probably why this never happened before. & Plus, his thing was huge so maybe that's what caused it. I don't know. But I'm really scared. WHAT'S GOING ON?!!

It is very easy to get a UTI after having sex and it very well might have the symptoms you are experiencing. You probably would not have any symptoms of pregnancy only a couple days after doing it. You should see a doctor.

just go see a docter it might be herpes but it dont sound like your pegnat

It sound to me like you have cystitis, its water infection, I get it sometimes after having sex. It feels like you need to pee all the time and when you do pee it can sometimes hurt and you only pee little amounts at a time. Drink plenty of cranberry juice and after having sex make sure go go for a pee. it should heal itself, you can by over the counter stuff for it, or go to you doctor. Hope it helps

It sounds like a urinary tract infection AKA bladder infection- If there is blood involved- it means that the infection has spread to your kidneys- See a doctor right away
