Cramps, cold sweats, puking

My cramps are always super bad on my first and second day but today (day 1) of this period was unreal. I have a very high pain tolerance but I was toppled over yelling in pain praying for the midol to kick in. Then I started to get cold sweats, it was like I couldn't get cold enough to stop the sweats then the nausea hit and it hit like a bus. After about 15-20 minutes of yelling in pain, sweating and nausea I puke and puke and puke til there's nothing left. I had to cancel all my plans. I was legitimately scared of my period. 🤦🏻‍♀️ I have no clue how to prevent this in the future help
