hi i am 25 years old, i have had endometriosis from the age of 18, so i have always had bad bowel movements, but recently i have been getting a really strong pulse in my slomach and a fluttering feeling like i was pregnant but im 100% not! (taken tests, and still have periods!) my stomach feels bloated and hard just very uncomfortable! also been getting bad headaches and felling sick with it!( still always go from consipated to diarrhea) i looked up up on internet and ibs came up, could it be this?? or any suggestions?? thanks
