What should I do with blood and blood clots in

Patient: Hello,I have a question regarding blood in urine. On Saturday (35h ago)I had a sexual intercourse, which was a bit hard and for few minutes my partner didn’t use condom because he did not notice it slid away (he is not my boyfriend). Fortunately he came outside but I am still afraid of some disease I could have cought. Yesterday (Sunday) I did not have any problems with my urine but today (Monday) I go to pee every 20min, it hurts, there is always blood and also blood clots.Could you please tell me what could that be?? Thank you very much!
