Last night had period like lower stomach pains, that are long, gets worse than better, steady pain lasting for about 3-5 minutes then stopped. Woke up twice at night from that happening, again a steady pain for about 3 minutes long then stopped. Now it’s happening again this morning where I have a non stop pain with highs and lows for a few minutes and then stops completely. What is this? Almost like I’m gonna have major diarrhea but I know my bowels are empty.
