Question cm

Hi ladies my gyn told me today that my hormone levels r normal n I m ovulating(my family Dr told me I m not ovulating).so it's gud news for me now there is only hsg test left behind which I m going to have next month.but my question is that I hv ewcm in ovulation days but not too much I hv very light cm in my cycle but it shows change like ewcm,cloudy etc so is it possible that due to very less cm I m not getting preg? (I m using preseed this month) n cm can effect fertility plz tell me ladies?
