I have been doing crossfit for awhile and once I got pregnant I continued to do it, but just modified some things. I'm 23 weeks now and have noticed a big change in what I can and can't do over the past 3 weeks. Anyway, on Saturday I did some lunges whhile carrying a 25# weight overhead. Afterwards, my lower stomach hurt when I walk. I had a pretty tough time getting around that afternoon. It almost felt like I strained some muscles. I took it really easy yesterday, but now my pelvic area hurts when I walk. Almost like I did something to the bone. Has anyone else had this experience? Did it go away? At first, I was worried about the baby, but he has been moving around and everything seems fine. I work with kids, so it's hard to stay off my feet and take it easy. Should I call my Dr?
