I normally get a positive OPK on CD 17. When CD 17 came and went and the test line on my OPK was only 1/3 as dark as the control line I went to google (though I think it's interesting they tried to get dark on that day). I googled: "negative opks after IVF". Turns out, the internet is filled to the brim with ladies who turned an OPK positive 1 week later than they normally would.
I woke up this morning, CD 25, wondering if I'd ever ovulate this month, took an OPK, and it was ALMOST positive. OPKs aren't hard to read (though most ladies on the internet at baffled by them). With HPTs, if there is ANY sort of line it's positive. On OPKs, the test line HAS TO BE AS DARK OR DARKER than the control line to be positive. So finally, mid morning on CD 25 I got a positive! (See below.)
I estimate my period showing up anywhere from 10-14 days from today. Which would make this cycle 35-39 days long! Oy!
