Did my water break in the tub?

I'm 33 weeks pregnant and was taking my nightly bath & finishing up when I felt like I peed a lot. This is normal if I have to go when I'm getting out I'll go and just rinse off. Then I started having contractions for a good hour, took a nap, they stopped. Then when I got up from my nap a few more came. My baby is moving a lot. If my water had broke would my baby's movements have slowed down and wouldn't my underwear be wet from leaking?
