Early miscarriage? PLEASE HELP

Courtney

Both my mom and my boyfriends sister believe it’s morning cause I had no bleeding, no intense cramping or cramping in general, I’m around 5 weeks pregnant but I just wanted to triple check

I went pee and passed a little piece of tissue

It’s red, not brown

I also got over a UTI, his sister thinks it could be from an infection or since I got over an infection

Or could be from my period cause I would’ve just got over it around this time

PLEASE help give me a peace of mind, it’s Saturday so I won’t be able to call my doctor until Monday!
