CM? peirod vs pregnant

Megan

can anyone tell me the difference in early Pregnancy CM and before peirod CM? today I am supposed to start but I notice for a couple weeks now I have had a lot more CM (doesn't stink) sometimes it's thick with almost a light greenish color but when I get it on my finger it's just cloudy white. and I also have some white lotion like CM. (I know I won't know if I'm pregnant unless I test) just want to hear your thoughts! thanks
