I just had my daughter(baby #2) on 2/20. This sounds like how my pregnancy was exactly. With my 3 yr old son, other than vomiting all the time, I had no problems. This pregnancy , though was crampy from day one, I too developed big, bruise-like spider veins, and if I laid on my side for more than 2 hours at night, I would wake up with a terrible sharp, stabbing pain, it seemed, just to the side of my uterus that I was laying on. Then, as I got farther along, my daughter would press her head into my pelvis, hitting nerves that would send pain shooting down my groin and sciatic nerve. It was a terribly painful pregnancy, there were days that I would have to stop and drop on all fours because it hurt so much. I felt like I was carrying a bowling ball in my bladder. God, I'm so glad I'm not pregnant anymore. While I don't know if this is common, I'd say that it's just part of why late pregnancy is uncomfortable for some women, but I would just mention it to my OB/GYN at the next visit. Be prepared though, not only did mine offer nothing(suggestions included) for how to help with this, they didn't seem the least bit suprised! So, I'm guessing by that that it happens more than I thought. Hang in there, it'll be over soon!
