Ovulation question.

Okay so we’ve been “trying” for 4 years and nothing. So we decided that we want to really try as in test and everything else. I have been to the Dr. And they said nothing seems to be wrong. But going again in a couple weeks. But if my CM is perfect(stretchy egg white) does that mean I am ovulation, about to ovulate or already ovulated? I just started my fertile window and I have the perfect CM, but no LH surge yet. So just a question! Thanks!!
