Quoting grizzy:" Those are Braxton Hicks/ False Contractions. You either feel tightening of the belly or period like cramps ... [snip!] ... with your Dr. to make sure it's not a threatened m/c. There should be no bleeding as well those two combine is not good news."
Quoting Angeleyes1372:" I didn't know it was possible to have them this early... I know I had them on and off when I was pregnant with my son after 20 weeks."
Quoting grizzy:" I didn't start having them til I think... 25-28wks. So I've never heard of them happening so early but, as long as your not bleeding than you should be fine."
