Popping feeling near cervix?

Has anyone else had this? I'm 33+2 and had this for the first time today. I have been kicked in the cervix tons of times and it didn't feel anything like this. It's not a sharp swift pain like cervix kicks. But more like bubbles popping and air being released but not in a gas like way. I don't even know how to explain it honestly lol

It comes with a ton of pressure though and it felt like I was genuinely just going to pop. For a moment I was afraid my water would break because there was so much pressure, but I knew that was unlikely lol

I tried googling it and could only find women who were 38+ weeks talking about it so I'm wondering if any of you experienced something similar!
