If u do an opk whilst on af will it show a test line?

[josephine3]

So im curious now after being a poas addict whilst waiting for af ( which i think i may have just started) i was getting faint lines on the hpt but running out of them so did an opk for fun and got 2 lines the test line was about half as dark as the control line. I kno thats not positive but iv never made one positive! Never seen one much darker. So i guess it doesnt matter now but im curious, what should an opk look like on cd1?
Thanks for any insight, sorry to jump on the ovulation board and bug you! X

It probably will. Mine showed a line when I was pregnant. And I don't ovulate at the moment since I haven't got my cycles back due to breastfeeding and I still get a line.
