Water broke? TMI PIC

I’ll be 36 weeks Monday and in honor of it being my birth month I decided to take a walk through the zoo (I heard walking helps labor) Our zoo is pretty big and about an hour in I went to the bathroom because my underwear and leggings felt soaked. We had sex before coming so I just chalked it up to that. I had no cramping but towards the end of my trip I had a lot of lower pressure which made me take a few breaks.

It’s about 4 hours later and my underwear is still becoming wet. I don’t know if everything is all in my head or if maybe I should get checked out. Should I feel cramping if it is my water? Should I see blood? I don’t know what to do.

*Added a picture of my underwear because it’s wet in the front and back
