Is abdominal pain before menstruation the same as abdominal pain in the early stages of pregnancy?

Abdominal pain before menstruation is not the same as abdominal pain in the early stages of pregnancy. Abdominal pain before menstruation will cause lower abdominal distension accompanied by low back pain. Some women will experience severe pain, while abdominal pain, dull pain and convulsion pain may occur in the early stages of pregnancy, but it is not very severe.
