THIS IS WHAT RESERCH HAS SHOWS
Cramping
during all stages of
pregnancy is normal, unless it’s accompanied by severe pain or bleeding.
During the earliest stages of pregnancy some women mistake the cramping for their menstrual cycle. This could be due to the fact that they may experience a little spot bleeding too. Spotting and cramping are classic symptoms of implantation, which occurs when the fertilized egg attaches itself to the lining of the uterus.
