Cramping usually onsets just before or during the menstrual cycle. It occurs when the muscles of the uterus contract and shed the uterine lining that has been built up during the previous few weeks. Prostaglandin is a hormone-like compound that triggers the contraction, leading to cramps.

However, in some cases, cramping could be present without periods, which could frustrate you. There are various reasons why you are cramping without periods, mentioned below are the same.

Some women experience cramping on one side of their lower abdomen during the ovulation phase of the menstrual cycle. The side of the pain depends on the ovary which releases the egg. The intensity of cramping differs from person to person and can be dull or sharp. Cramps usually last from few minutes to few hours. In an ideal 28 days’ cycle, the cramping can occur 10–14 days before menstruation begins, indicating the release of the egg.

2. Pregnancy Or Ectopic Pregnancy

Ectopic Pregnancy

Called as “implantation pain,” the cramping that occurs during pregnancy is an indication that the fetus is attaching itself to the uterine lining. Cramping is also prominent during the first trimester and usually sets in around the 5th and 6th weeks of pregnancy, when the uterus expands to accommodate the fetus. Spotting is also evident in some cases.
