fluid leaking or something else ?

Megan
Me and my husband took the kids out to play at a play place in the mall where we live, I'm pregnant with baby #3 and am 36w and 6 days. Just waking around watching the kids I noticed my hands started to swell pretty bad , but it does that off and on sometimes. And I'd been having what felt like pretty frequent Braxtons . Then I felt like I really needed to go to the restroom I went and my underwear was soaked though. It had no smell no color. We come home and I change and put on a pad it's damp within just a few minutes of wearing but I'm not having any consistent pain off and on but not really a pattern. I'm going to call my doctor but just wanted other opinions as well on what it could be.
