Hi Sarah -
What you see is definately mucous that is put in place in your body to help it - but a lot of us have excess mucous (usually candida) that can lead to a myriad of problems if you don't get rid of it. To learn more about this, you can go to the Candida Forum
here on curezone. Bottom line is, you have too much mucous in you that needs to come out and you're getting it out - that's great! Keep it up!
