I took a hot shower and when i got out i sat on the toilet to pee. When i got done peeing i wiped and saw that i had thick drown discharge, then i wiped after that and only had a small amount that was kind of pink, but havent had it since. I was already at the hospital today for really bad back pain with contractions, but got sent home from not dilating more than what i was, and for my water not being broke. Im still have the back pain with contractions, but should i be worried about the discharge i had, or is it probably just my mucus plug?
