Varies: Ovulation happens 14 days before the period starts. Ovulation can happen from 7 to 21 days after the period starts - but is always 14 days before the next period. Sperm can survive and still fertilize an egg for up to 6 days inside a woman's body. After ovulation the egg is "available" to be fertilized for about 24 hours.

Usually day 14: Usually day 14. Yes you can ovulate early. Sperm can survive 3-7 days. Egg is usually available about 24 hours.

Lots of ???: 28 day cycle likely around day 14 (can confirm with ovulation prediction kits). Sperm viability is usually a couple days, but they begin dying off or become immobile within 24 hours. The egg is most likely susceptible to fertilization while in the fallopian tube and transport takes 1-3 days. However, we do see women conceive up to 7 days post ovulation. The chances decrease after a couple days

There are other ideas about some of you questions. Current literature supports that ovulation happens 14 days before the period. Ovulation comes from 7 to 21 days after the period starts - but is always 14 days before the next period. Sperm can survive and still fertilize an egg for up to 6 days inside a woman's body. After ovulation the egg is "available" to be fertilized for about 24 hours

Ideally d14: There is definitely some variation +/- 1-2 days, but ovulation usually occurs 14 days from the first day of the NEXT period. Sperm can survive 5-7 days in the cervix. The egg is more temperamental, makes the trip from your ovary into the tube at ovulation, few pregnancies occur within a day of ovulation.
