Water leaking?? Maybe just urine? Or discharge?

Megan

So yesterday, I woke up had what I assumed to be a lot of discharge in my pants. So I took a shower. My SO, son, and I went to Chuck E Cheese and out to eat. My SO looks at me and tells me my pants are wet. I didn’t feel any of it. My underwear soaked and pants are a little wet.

But nothing today. Just a little sick feeling and crampy. What should I do?
