38 weeks, leaking fluid?

.

So the last few days I’ve had watery discharge. It’s not a lot but I’ve noticed it’s def. thinner. Last night after I peed I was sitting in the toilet and I was about to get up and I felt a warm trickle, but then it never happened again. I laid down for a while stood back up and nothing. Today I’ve had more cramping and I felt a little gush, I went to the bathroom and it was watery discharge. Has anyone experienced this and it not been their water ? It doesn’t smell like urine. I had a panty liner on and it’s def. wet. I’m only getting occasional small gushes a few times a day. I’m waiting for my OBs office to come back from lunch to call.
