Did my water break? Or is it pool water?

Me and hubby were trying to get frisky in the pool and it wasn't working out. So we go inside and it's about ten minutes later. I lie down and I feel a sudden trickle of fluid come out of me. It felt more than a trickle. The bed was wet from it and it's still trickling out. Could it be pool water? It didn't have a smell. Our pool is salt water and it has a very distinct smell. It's been about thirty minutes since it's happened and I still feel like I'm leaking something. I'm 29 weeks and 3 days. I feel very off.
