Brown.

Yesterday I went to the doctor for my 38 week appointment and he stretched me from a 1 to a 2, and I am 60% effaced. I had brown spotting all day which was normal since he messed with my cervix, but my question is...I woke up this morning and I had brown watery discharge. What could that be? Could it still be from yesterday? My appointment was early in the morning I didn't think I would spot for this long?
