panicking, I need advice!

I'm 12 weeks and about 3 days pregnant as of today, my fiancé and I went fishing earlier and everything was fine all day, I was sitting down from about an hour and stood up so start putting the poles and stuff away and felt like I was peeling myself, but I know it wasn't pee, it was like watery but I'm so paranoid something could be wrong. please tell me what's happening? 😭 I'm so scared.
