Can a female conceive on the 12th day of ovulation?

14 days from period: you ovulate 14 days from when your period starts so if you had periods 26 days apart then you would ovulate on day 12 Normally it is 14 days on a 28 day cycle But day 12 of a period is possible

When to conceive?: The greatest likelihood of conception is with intercourse during the time period from several days prior to, and including the day of, ovulation. Ovulation is when the ovum (egg) is released from the ovary to await fertilization over the next 24 hours. There is uncertainty in knowing the exact day of ovulation. The rhythm method of contraception (days to skip sex) is less reliable than others.
