Trying to Conceive

I am so confused about the CM because I heard when is like egg white it means you are ovulating and with my husband we have been trying to do it that way but it seems not being working. We being following what days I should ovulate and how the cervical mocus looks like. I dont get any symptoms when I ovulate, does anyone knows what are the symptoms or if you had some of them? I NEED HELP PLEASE!!
