Hi Katy
sorry to hear you didn't get any *hugs*

All I know is that EVERYONE ovulates 2 weeks before there period. No matter what the length of your cycle. people with a long cycle have the extra days between period and ovulation. and those with shorter have less days between period and ovulation.

so the only thing I can say is you wouldn't have ovulated early unless the days were misscalculated.

sorry I dont know very much at all on IVF.

good luck in the future!!!
