Ok so my doctor told me a few months ago that I should start taking OPKs the day after AF went away since I never know how long my cycles will be...well for the past 4 or so months I have had AF for 7 days! Well today is cycle day 6 and AF left yesterday! So should I wait until cycle day 8 or should I start doing OPKs now? I have plenty I just wasn't sure if since AF was shorter if that ment that I might ovulate earlier??? That would be so awesome if I did since DH is suppose to be leaving around when I should ovulate if it was like my last 2 cycles! TIA!!!!
