TMI! 36 weeks

I am almost 36 weeks pregnant and went into early labor a few days ago. I have lost 2 huge chunks of my mucous plug and have been having lots of cramps and back pain. Last night I thought my water was leaking so I put a pad on and I’m having discharge that looks like this. To me it kind of smells like discharge you get when you get your period. It doesn’t smell like urine at all. Is this normal? When I was at the hospital they tested me for infections and tested my blood and all came back normal. I took my pad off to take this picture and stood up and now my underwear are wet and they don’t smell like urine either..

And now 10 minutes after I posted this, I lost another huge chunk of plug! I didn’t know our bodies held so much!
