How do I know if my water broke?

I sound really silly for asking this but how do I know if my water broke? I’m a FTM.

I was sitting on the toilet earlier( taking care of #2) when all of the sudden I heard a pop and a lot of fluid came out. I thought it might be pee but it looked thicker and kinda slimy. Almost like the fluid they give you in the hospital if you’re dehydrated. If that makes sense. Anyway, I went back to bed and sat up for about 10 and went back to the bathroom. This time a lot more came out. I still couldn’t tell if it was pee or not. I’ve read where you can’t push to make your water come out but I felt like I was pushing regardless. Is this my water breaking or something else? Ever since this has happened my stomach feels like it’s doing flips.
