Ovulation cycle calculator
For women who have a 28 to 32 day menstrual cycle, ovulation can take place between days 11 through 21. Ovulation cycle can be calculated by starting with the day the last menstrual period (LMP) starts or by calculating 12-16 days from the next expected period. Most women ovulate anywhere between Day 11 – Day 21 of their cycle, counting from the first day of the LMP. This is what many refer to as the “fertile time” of a woman’s cycle, because sexual intercourse during this time increases the chance of pregnancy.
Pregnancy begins if “implantation” occurs. If the egg is not fertilized, it will “expire” in about 24 hours. Without fertilization, levels of certain hormones will decrease , causing the lining of the uterus to break down and shed – otherwise known as menstruation, or a woman’s “period”.
