When does ovulation occur

Ovulation occurs when a mature egg is released from the ovary, pushed down the fallopian tube, and becomes available for fertilisation. The lining of the uterus has thickened to prepare for a fertilied egg. If conception does not occur, the uterine lining, as well as blood, will be shed. This secretion is the menstrual flow. The diagram below details a woman's average monthly cycle.

Counting the first day of a woman's menstrual cycle as Day 1, the most fertile period of a woman's cycle (where there is a higher probability of getting pregnant) is between Days 12 and 18. Thus, women with a very consistent cycle will be most able to get pregnant for a short time about 2 weeks before her next period comes.

However, many women mistakenly estimate when their next period will come. Other women have such irregular menstruation that pinpointing their ovulation is more difficult. In either case, becoming pregnant unintentionally is common. Be aware, that ovulation can occur at various times during a cycle, so some women can conceive at very different times in their menstrual cycle. Remember also that sperm can live for at least 3 days.
