how accurate are due date reverse ovulation calculators?

Varies: Depends how accurate your due date estimates are. If you have a super-reliable dating then the reverse calculation is "pretty good," like within 3-4 days. If your EDD is +/- 2 weeks as it often is, then the reverse calculation will be not useful. Good wishes.

A 45-year-old member asked:

If you have short periods does your ovulation date come earlier?

Generally yes: Ovulation occurs around 14 days before your period regardless of how long your cycles are. There is a little variation in this, but not much. So if you have a 22 day cycle (day 1 is the first day of your period), you ovulate on or around day 8.

Conceived 10/11/12?: Due date can be calculated from conception date, so if conception is 10/11/12 (oct. 11th), then the baby is due on the fourth of july!

Not likely : Ovulation is 14 days before your next period. Those dates don't add up very well.

Ovulation: Ovulation happens 14 days prior to the menstrual cycle. Your wife's cycles are approximately every 34-35 days. Therefore, ovulation is taking place approximately on day 19-21 of the menstrual cycle. Another way to check for timing of ovulation is using ovulation predictor kits.
