I would call and double check with a nurse or someone at the hospital or clinic. If it is like a "loogy" it could be your mucus plug, but it could just be normal! Just call and double check just to put your mind at ease!! Let us know what happens.
EDD with baby #1 for hubby and I September 21st, 2003! It's A BOY!
I am pregnant with #3 and I think that unless you had sex recently, this could very well be part or all of your mucus plug. I would not be surprised if you weren't dialated to one. This is a bit early but I know a 2 ladies who were dialated at 30 and 32 weeks. Definately follow up with your doctor. They will probably do an exam and take it from there! I KNOW that it's easy to get worried when something out of the ordinary happens but let the doctor check you and probably put your fears at ease.
