Yes it is! Pregnancy-cramping can occur later during pregnancy and not necessary in the initial months of the pregnancy. The muscle scamps only take place as and when the uterus begins to develop. However, during the second trimester, you should have the lowest amount of cramps compared to the first. This results when the muscle that is responsible to protect the uterus starts to stretch out, a round ligament. In case the cramps fail to lower themselves in the intensity, you must contact your doctor immediately.
