Okay so first of all I had protected sex this Friday. I woke up feeling fine on Saturday, but soon started to feel like I needed to urinate frequently and it would burn and barely anything would come out. I figured it was a UTI, and started to drink fluids. That night I went out to a party and drank a little alcohol and started to feel horrible cramps so I went home. This morning I woke up with a headache, and more importantly, I'm urinating blood. There's no pain. It's not my period because my period is regular and it ended 2 weeks ago. What could this be? I'm super scared... I'm literally bleeding like I'm on a period.
