So Last Night I Ate Two Tortillas With A Little

So last night I ate two tortillas with a little bit of butter right before I went to bed because I was hungry. 2 hrs later I woke up with severe pain in my stomach and felt like I needed to poop nothing came out and I was sweating alot and almost felt like I was going to faint. I had to go back and forth to the bathroom at least 5 times. The 5th time I was actually able to pop this time and relieved my stomach pain... what could have been wrong? My mother assumes it because I should be starting my menstrual cycle soon but I've never experienced something like that before.
