So I did a cycle of femara 2.5mg last month on days 5-9 and started opk testing the day after finishing that and got high fertility results from CD 11-16 then peak fertility on CD 17. Well I'm on my 2nd round of femara this month and I just took my 4th day of opk and all 4 have been negative so far 😟 so tomorrow will be my CD 14 and I'm really hoping I get a positive opk then. Is it normal to ovulate different times each month on femara? Has this happened to anyone and they stI'll ovulated? I am starting to get worried that femara might not work this month? Is that possible?
