I tried searching because I'm sure there is already a topic on this but I can't get the search to work! Anyway I am on my first round of clomid, 100mg CD2-6. I started doing OPKs on CD10 and right away I was getting lines, not positive but almost there, then they started fading, now I'm CD14 and I'm getting only very faint lines. I'm confused, in the past when I've done OPKs (not on any drugs) I was getting faint lines on around CD12 turning to positive by CD14 like clockwork. I'm trying to do an IUI this cycle too and now I'm worried maybe I ovulated really early? Or is it just delayed because of the clomid and those faint lines I was seeing was just left over from the Clomid time? I really want to schedule my IUI and I'm getting impatient and frustrated that I'm not seeing any progress in my OPKs.
