Help. Super unusual period.

Ca

So started my period yesterday and usually it’s not too bad. Yet I almost passed out due to my cramps. Around 5AM was this morning I woke up in unbearable pain, my stomach hurts to the touch and I don’t want to move because I feel like I’m going to throw up. Everything is also really “liquidity” and runny, super strange for me. So does anyone have any tips to help this? Especially since I have school today.
