So I'm 31 and have four children already. Hubby and I are trying for our second baby together and we have had no luck. I stopped more a back in November last year and my cycles have no been regular at all. It varies between 25-30 days when before I was always 28 days. I've done opk tests and have not had a positive one yet and I don't get any ewcm. What else can I do to see if I'm ovulating or even if I am?
