Trying to conceive & orgasm?


Ok so I know that when you ovulate you get that egg white stringy discharge. But I only get that when I make myself orgasm? I don’t orgasm when I have sex. I can only orgasm when it’s clit stimulated with a vibrator... and when I do orgasm with my vibrator on my clit, that’s the only time I see the egg white stingy discharge....? I’ll see that anytime I cum whether I’m ovulating or not?? Im confused. How am I suppose to know when I ovulate if I never get that discharge, only when I orgasm?
