If the cramps are coming and going at intervals then it is best to have a check up. At times if the cervix is shortening then it can result in uterine cramps which come at intervals.

as uterus is expanding, it is common to feel cramps. but consult with gynec if its too much pain, or there is spotting or discharge... thanks for the tag <font color ="#3b5998"><b> @63724497649d8300169033e9 </b></font>
