am I close to labor!? tell me your experiences

Ka
Tomorrow I'll be 38 weeks. I've had a lot of watery discharge the last few days. Tonight, my foot swelled up worse than it ever has. So after some BH and cramping I went in to pee and my discharge is now a light brown but still in abundance. There is soooo much pressure when I pee. Last Thursday I was checked and was 60% effaced and not dilated, Sunday I was 75% and a fingertip dilated with contractions 2-3 minutes apart (but not active labor). Does this sound like my bloody show?
