ovulation question

Ch
Okay this is a complex question. My husband and I started ttc about 4ish months ago. Prior to this I used to be able to tell when I was ovulating very easily due to my CM. Now that we are having sex all the time I suddenly can't tell at all if I'm ovulating. Has this happened to anyone else? I'm a little worried that there is some weird correlation that the more sex I have the less I ovulate, but that doesn't make any sense. 😩
