Ovulation is how long?
Ovulation is merely the point at which the ovary releases an egg. A woman is fertile roughly 24 hours after her egg is released. However sperm can survive in cervical fluid for up to 5 days before ovulation, meaning a woman can be potentially fertile for as long as 6 days.
How can you determine your ovulation cycle when you have been on the pill for so long and you have not had a period in two years?
A normal ovulation is when your LH phase is between 10-16 days long. This phase can not be counted from the 1st day of your period rather is is counted from you ovulation date to your period. This shows that the uterus has a healthy environment for immplantation. To determine when you ovulate you must temp or use OPK (Ovulation prediction kits)
