Weird feeling

So I used to get this weird feeling whenever I would roll over to my side like the baby was having to settle back down or something. I don't know how to describe it but it was just a gross, uncomfortable feeling. Well, now that feeling is also every time I stand up and walk. It's just such a weird thing. I don't know if my description helps at all, but has anyone else felt something like this? It's almost like just feeling super bloated but also really heavy.
