Fluid measuring 10.25? Mucas plug? Labor near?

Story time-

Ok, so I am currently 36.5 days with 3rd baby.

My first came when my water broke at 38.3 days had a c section due to failure to progress after 27 hours, second baby came at 36.4 days when my water also broke had him via c section due to failure to progress on my own.

On Sunday, 36.4 days at 11 am I had about 3/5 puddles of what I thought was amniotic fluid and went to the hospital. All test came back negative, went home and at 11 pm that night I had 6 puddles within 5 mins (picture of one of the spurts I had down below. Went back to the hospital and still negative, how does someone “pee” there selves that much. Every time it’d happen I already have had peed. My amniotic fluid levels on the ultrasound were a 10.25, is that good for my gestation stage? Today at 5pm I had what I believe to me my mucas plug coming out with a little bit of blood (not much). I’ve never lost mucas plug or had any type of blood with either pregnancy. Is this from being checked so much at hospital? Or is labor near?
