what could this be?

last year when I went to my yearly gyno appointment, I expressed to my doctor about my painful periods. something that i’m unsure is normal.

about day 2 or 3 of AF, occasionally either every month or every other month, I will wake up in the worst pain imaginable. so awful, I will vomit, have diarrhea & constipation, and sometimes even faint. It makes me feel feverish as I get so hot and sweaty, and I will be laid out in the bathroom hugging the toilet for hours. Eventually, after I lay down, my cramps will then come and go in “waves” and once I know I won’t vomit anymore, I will take some aleve and try to fall asleep. Once I wake up, I feel completely fine.

This doesn’t happen every month, but quite often. I told my gyno, and she just expressed I time my medications better.

Has anyone experienced this and had an underlying condition?

I’m in my TWW, and if I am not pregnant, I will make and appt and I want to try to get an ultrasound, but I’m just curious.

TIA!
