Trying to work out if I DID ovulate ... the OPK says the test line will be as dark as the control line, and if not as dark then no LH surge.

I tested Fri, Sat, Sun and Mon as increasing CM on those days.

Line started off faint (feint?) but by Sun was much darker - but not as dark as the control line. Still, it was very obviously there, and I didn't need a high voltage magnifying glass to see it ! CM peaked on Sunday too.

Any thoughts. The T line wasn't as strong as the C line, but not far off it. So I "think" I did, but maybe I'm kidding myself? My cycle is pretty weird at the moment (I'm far from a CD28er), so it's entirely possible I almost - but didn't - ovulate if the OPKs are spot on.
