So last night I had contractions for 3 hours after having a membrane sweep in the morning. This morning I was getting ready to take owen to his horse lessons and I wiped this string of TMI but bloody looking mucous. Then it happened again when i got us home from horse lessons. I'll put a pic in the comments but is that my mucous plug or bloody show? Should i call about it?
