If i remember correctly it sounds like the start of the mucus plug coming away,but its been nearly 16 years :) but i wouldnt worry to much about it,since it can start coming away weeks early,slow process for some.I dont know about the green though,im sure other ladies here be able to offer good info.
I've had a discharge for a few weeks now, this weekend i got a huge piece of discharge, which i am assuming is at least part of the mucus plug. it's clear and white, very snot like. My doctor did tell me though that if it was greenish in color that could be an infection or bacteria. I would call your doctor right away and let them know. It could be nothing, but it wouldn't hurt to find out!!
hi i have now had my son since i put this post on but i lost my mucus plug and it was like green snob but i found out my sons bowels had moved inside me thats why it was so green thank you for your comment anyway
