I just saw my gynecologist today about excessive cervical mucus and what appears to be bits of my mucus plug. I was freaking out because I never had so much mucus with my first two pregnancies and I thought that it was a sign that something was going wrong.
But my doctor told me that it's absolutely normal and that cervical mucus during pregnancy usually increases with each new pregnancy. Apparently, it's even normal to see mucus plug in the first trimester since it's something that's constantly being produced. I'm glad I went in though, I feel so much better.
