I don't know what is causing this pain but I was just laying in bed and I started to cramp up. Then it got worst I took ibuprofen to see wat happens nd the pain continued and then stopped for 2 min and came back again. I never felt this worst in cramps before it hurts bad. It even made my face red and the pain was so sharp I almost threw up. I haven't had my period for couple of yrs cuz of implanon but it expired a yr ago and still in my arm. Don't have insurance yet to remove it.
