New to this...bowel problems.

Hi everyone, I'm Cassi.

Im 32y and eversince I can remember since I've started my periods, I'll get these random times where when I'm know I'm gonna have a bowel issue, it's like I get this intense band of pain that goes from the top of my intestines all the way down to my groin almost like my intestines are contracting. I get really sweaty, but I'm cold and hot at the same time and I get really weak to the point where I feel like I'm either dying or about to pass out. First, it will. Be kind of a hard stood and then towards the end it'll be very loose stool. I forgot to mention the way I breathe it's like I'm doing lamaze breathing. It's not all the time but it's maybe once a month. Sometimes it skips a moth but it makes me scared to poop. After I am done I am fine. Yesterday I had that same attack and I actually passed out on the toilet this time at the store. The way I felt I thought my heart was gonna stop. Fast forward to today and I feel like I am still feeling the repercussions from it, sore stomach, intestinal pains like knives, sore hips and weak. A couple of weeks ago I actually went to a new gyno (i hadn't been to one since 2022) and when he did the internal exam, he pushed up with his finger and I shot out of the chair. He said that he's almost positive I have adenomyosis I just need to get a ultrasound because of how sensitive my uterus and cervix is. My question is has anyone had this feeling when they had a bm?
