I think it's pee?

Im 27 weeks today!! Yay!! My concern though is I sat up off the bed and felt like I tinkled myself a bit. I went to the bathroom and noticed most of the center of my thong was wet. There was also discharge on my undies which I'm used to. So I thought maybe it's that but it was pretty damp so I (so weird lol) took a sniff and it smells different. It smells very sweet but I think maybe it was pee Bc I had drank sweet tea earlier so maybe that's why it smelled sweet. Anyone else have sweet smelling pee? I thought lee usually smelled bad but maybe not always?
