Periods are the worst

Ugh, so I started my period yesterday and it is one of the worst ones Ive had in a while. Usually the first day I start it’s kinda spotty and slow then the second day it’s bad. For some reason, I just woke up cramping (2 days early) and I went on my walk I take every morning and it just came out like crazy. My pants and underwear had blood. I for some reason have bad diarrhea and my cramps are out of this world. I also am so irritable I feel bad for my fiancé, I had an attitude with him for no reason before he went to work this morning. I feel like I just need to sleep all day but in the real world that’s just not possible. If you can’t bring a heating pad with you to work, what are other options to help this? Ps. Birth control never helped me, just made them worse.
