Before I started TTC I never gave any thought to my cervical mucus (CM). To be honest, I never really noticed it. I mean, I knew that from time to time I would have some sort of discharge, but I guess I knew it was normal and never really thought about it. It wasn't until one day when my sister who was TTC at the time told me about egg white cervical mucus (EWCM), thought I didn't know the term for it at the time, she basically said that when you have lots of discharge and it looks like egg whites it means you are fertile. I never put any more thought into it until I started TTC.
I never realized there was so much to know about CM. There are different types of CM and they can help you figure out where you are in your cycle and how fertile you are.
