GO TO THE DR.... PLEASE. I called my Dr's office and complained about the same thing, the nurse said it could just be my legiments stretching and after having 3 kids I would feel it a lot more than I had with my last 3 pregnancies.....NOPE. I dont mean to scare you but I would want anyone who was in my position to go through what I'm going through now. I have whats called Placenta Abruption, its where the placenta tears away from the Uterus. Dr's dont always know what causes this. But I am now 22 weeks and they were able to detect it early enough to put me on bed rest for the rest of my pregnancy and I will probably not deliver after 32 weeks and will have to have a C-Section. So, when in doubt dont hesitate to get checked out, its better to find out that its nothing rather than something. I hope for your case that its just your uterus stretching!
