What Causes Blood During Urination After Having Sex?

this is my second time i have had sex. my first time i bled a lot. the second time it was only a little during intercourse but then the morning after there was blood in my urine, i had to wear a pad and it is worse than my period. i only have blood when i pee and when i go pee it is mostly blood but theres no severe pain and just a little cramping throughout the day it has been a week, im tired and have no appitite. it is not my period because my cycle was the week before i had sex (period ended a day before). i am in a low dose birth control (junel fe 1/20) that i take on the dot every day. what is wrong? should i seek medical help? is this normal? could i have a uti? could i be pregnant? if so how soon can i take a pregnancy test?
