false alarm 😡

Hanna • TTC baby #2.
So before bed I was having really bad back pain. I went to bed finally. I was woken to what I thought was me peeing my pants. Or mucous. I got up & both my panties & shorts were wet. So I went pee. Then told my bf I'm gonna change & see if I leak anymore. I started having back pains again. Before I got in the shower. I felt even more pressure & pain then I felt stuff run down my legs but I felt like I was peeing. The way it came out. If that makes sense. So I got in the shower nothing else happened. Before the shower I went pee. So I really don't know what happened.   Any thoughts
