I'm currently 4w6d, and am having some pinching pain, mostly on my left side, sometimes on my right. It's not painful, it feels like a quick poke, I read that it can be round ligament pain, (even though I'm so early, this is my second child and I've read that it starts sooner with baby number 2). The other day I had sneezed and felt a sharp pain in my left side that only lasted a few seconds so I'm assuming I've started some round ligament pain, but I'm worried about an ectopic pregnancy, or maybe a cyst? My U/S isn't until I'm 6w4d, is that too long to wait? I don't want to keep bugging my OB for no reason, I'm such a worry wart!
