Anybody know what I'm feeling?

I'm currently in my TWW and a couple days ago I started feeling slight cramps in my pelvis, nothing too intense. The weird thing is every time I sit down with any kind of authority I get a quick achy twinge in my pelvis and then it's gone once I'm sitting. Anyone else experienced this? Anybody know what it could be? Thanks!
