Not bh but cramps?

My stomachs so tender to touch. I’ve been getting a lot of bad cramps like period cramps? Is that normal

I’m not dehydrated I drink nothing but water at least a gallon a day

When I drink water it kind of helps them but they still continue just not as bad

And lower back pain on just my left side comes and goes

But I have noticed after I pee it’s like my discharge is more watery?
