Period pain help!!

Can anyone offer any solutions for period pain? It’s honestly AWEFUL, it’s only like this on the first day but It honestly hurts so bad I just want to curl up in a much less walk around and I have to go to work in a few hours. I’ve taken three Tylenol and I don’t feel any different at all. I have drank so much water as well and still feel AWEFUL. I’ve tried ice packs, then switched to a heating pad, still feel awful. I know it’s only for the first day but how do you guys cope with the heavier days of your flow?
