Ovulation Predictors (tmi warning!)

SGC, if your cycle is around 34 days or so, you are likely ovulating around day 20.

Cycle lengths show significant variation from woman to woman, but a more consistent measure is the ‘luteal phase’ of the cycle, which is the time after ovulation until you get your period. This is almost always 14 days (unless you have a luteal cycle issue) so chances are that you are ovulating close to day 20 which means that days 18,19,20 are most likely your most fertile.
