So in that case, since your period came late, what that means is that you did not ovulate when you thought you did and had stopped having attempts long before you actually ovulated (right?? correct me if I'm wrong) Periods never come "late" (unless it's a miscarriage) Only ovulation is late, and then your period is tacked onto the end of your ovulation. So a late periiod means you ovulated later than you think.

Always keep going with the e4d unless you are 110% sure you have ovulated.
