Drinking water making me gassy

All week I’ve been getting gassy and crampy from drinking water at work I thought maybe it was my reusable bottle but I drank from a disposable unopened bottle today and it happened again. I haven’t been drinking water cuz the cramps are too much! What the heck is going on! It’s literally just with water. Food isn’t bothering me.

What’s stumping me the most is that I have not changed my water brand or water drinking routine. I’m not chugging. I just sip through out my work day. But now I’m barely hydrating cuz it hurts too much. Just started this week! So strange.
