Can someone please help and tell me if this is normal (TMI w/ Pictures)

So on Wednesday my SO and I had sex. And when I got up after to go to the bathroom I was bleeding. And it was on the mattress and on Jim’s it was bright pink and there wasn’t really any pain. The next day there was a little on the tp when I wiped but by 11 there was no more blood at all. Yesterday I got a call from the dr saying I have a uti and they prescribed me Cefuroxime, 500 mg twice a day for 5 days. I just started it today. And right now after dinner I went pee and in the bottom of the toilet there was, what looked like a booger.

Is this normal or should I be worried? I don’t have a number to call after hours. I have to wait till Tuesday to talk to my dr and I’m trying not to freak out.
