I'm only 8w4d, but I woke up yesterday to the worst rib pain ever! I know as the pregnancy progresses later on, things move around a whole lot more.  It feels like someone beat me on my ribs! Left on especially feels bruised and sore. I didn't do any exercises or move in a way that could cause it. The only thing I can think of is maybe all the vomiting I've been doing (I have Hyperemesis Gravidarum), but that's been nonstop for 2 weeks now, so I don't know why now it could start causing pain. Anyone else  experience this this early on?!
