Feels like food poisoning when my period starts?!

My period started today, at first I was glad I didn’t wake up in the middle of the night from cramps, maybe this period wouldn’t be so bad... I got up, went to get some ibuprofen for the mild cramps, then out of nowhere I felt dizzy, nauseous and stomach pain. I then spent the next hour keeled over on the toilet, drenched in sweat and trying to focus on breathing to distract from the extreme stomach pain, it felt like really bad food poisoning, BUT this has now happened to me twice on the day that my period starts. Has this ever happened to anyone else??? My Dr. said that my cycle can cause symptoms such as nausea, vomiting, diarrhea and cramping, but it was SO bad, I’m having a hard time believing it was all just due to my period starting. Anyone that can shed some light on this, I would really appreciate! Just wondering if anyone else has anything like this happen??
