Popping sensation but no water came out?

So, I was trying to 💩 (sorry tmi) and I felt the oddest popping sensation towards the lower part of my belly pretty close to my vagina, not once but twice. Before that I had been feeling a lot of pain, she was moving a lot so I assume that’s the root of the pain. After that sensation, the pain just went away. This is my second daughter, and my water broke after i was induced on its own with my first wnd it was a very similar sensation but I had a rush of water afterwards and nothing just now.

It was such a strong sensation so I don’t know what to think. Not just a little bubble pop.

Any help? I’m in the tub now to try and relax, but in worrying.
