Blood after sex

okay so i had sex for the first time last friday. it was kinda unexpected but it was still good. anyway, when it first happened he didn’t put on a condom. he didn’t come or anything and we finished with a condom on. it was the last day of my period so i bled a little but not too much. and i didn’t notice any blood the next day. it’s been about 2 days since it happened and i just noticed a little bit of blood when i peed. is this normal?
