No. Brown in your mucus plug is old blood and normal. You go to the hospital if your water breaks and it is brown.
Normally if you have a bloody show in your plug that labor is nearing. But I never heard having to go to the hospital cause of its color. I mean you can call an speak with them but I don't think you need to go in
I haven't heard that. Your mucus plug can be several colors. It can be pink, brown, and/or like a yellowish color.
