Calculating ovluation date

August 27, 2008

Hello Doctor,

My cycle for the past months have been 31,32,30,30,31,32,31,30 and the recent one was 27.

How should I calculate the ovulation day?

Thank you!

In your case, best is to use home Ovulation kits since the cycle length varies, which is normal..Usually, one ovulates 14 days before the next period start day.
