Fertility Week

Leah
I'm currently in my fertility week and should be approaching ovulation. This is my second round of provera and Clomid combo. Last month I had an ultrasound done that somewhat showed where I had likely ovulated; however, none of my opts were ever positive. Same thing this month, two more days like in my ovulation period and no dark lines...they aren't even progressively getting darker. Anyone ovulate later than glow predicts?? Any cycle buddies interested in following with me?
