I have lower back and abdominal pain feels similar to the period pains but in between periods?

I’m a 23 year old female. I have been having lower back and abdominal pain that feels similar to the period pains I get, but it’s happening in between periods. The pain is so severe that it causes my teeth to chatter. I am taking the contraceptive pill – rigivedon. The pain only lasts maybe 10 minutes and is at random but does interrupt whatever I’m doing at the time. The pain is all around my lower back and lower abdomen- not just one side
