Counting just in case, did my water break?

I just woke up to go use the bathroom. It's about 2:37am and I was holding my daughter when I woke up. I got up to put her in her crib and noticed that the left side of my shorts were damp from my vaginal area on down. My son is also sleeping in the bed with me, he's 4, so I assumed maybe he had an accident but the bed wasn't wet, he wasn't wet and I didn't smell the overwhelming smell of pee. So I went to the bathroom to pee and it's been a couple hours so it's a lot. I try giving a little push to see if anything else comes out and nothing does. I start getting small contractions and it occurs to me that maybe, my water is broken. But there isn't any wet spot on the bed but I'm not too sure if that guarantees anything because I've never had my water break with either of my previous pregnancies. I still counting my contractions but they are small & my bf is at work so I don't wanna make him leave if it's a false alarm but he may have too. Just need some insight on what to do, help!
