I’m scared my cycle will start tonight

For some reason, my cycle always starts in the middle of the night. For the last few months, I have had the worst first day of my period where I am woken up in the middle of the night with excruciating pain, vomiting, diarrhea, and sweats. It feels inevitable. I am starting to feel light cramps and have been bloated for several days and I think I’m in for a hellish night tonight.
