Early signs of a miscarriage?

I'm currently 5 weeks 2 days, my partner and I had sex tonight and I've been non stop peeing since but as the sperm & cm is coming out (just in little bits as I pee) it's coming out stretchy with streaks of blood. Just very light streaks though🤷🏼‍♀️ is this normal? This will be my first baby and im very worried that something will go wrong.
