I am so confused, I've been TTC for 3 years now with no success. They say the most fertile CM is egg white like so that is what I was basing my fertile window off of. However, I've started to use opk to try to figure this all out. When my opks become positive my CM is dry and when my CM is egg white my opks are negative. Which should I base my fertile window off of, the opk or my CM? please help!!
