Is this normal?

Hi all! The first few years that I had my period, I did have really awful cramps. I had to go to the doctor monthly for a prescription just so that I could make it to school. Over the years it got a lot better, still always cramps, but never debilitating anymore. Now as an adult, today I woke up with the worst cramps I have had in years, extremely heavy flow, and relentless nausea. I have not stopped vomiting and had to call out of work last minute. I assumed that ibuprofen and some stomach relief tabs would fix my symptoms and I’d be able to make it. I guess my question is: has anyone experienced or know if it’s normal to have a cycle like this randomly? Is it possible that it’s just a bad month, or stress from the holidays that’s made it come on so strong? Or do I need to contact my doctor ? Thank you ladies! Any advice would be of comfort!
