Before the next menstruation, ovulation occurs 14 days before for most of the woman. It is difficult to know when the women will start her next menstruation. If a woman has a regular period then it is easy to calculate the days of ovulation. The days of previous menstruation must be used as a starting point. It is very important to know that four days before and after ovulation the egg can be fertilised and it is not the safe time for you to have sex if you are not ready to be pregnant.

The menstrual cycle is of 28 days and is counted from the first day of menstrual bleeding. The menstrual cycle is divided into three phases:
- The Follicular phase: It is a pre-ovulation phase where the follicles in the ovary mature and this phase ends with ovulation.Here the Follicle-stimulating hormone is secreted and Estradiol hormone is atwork.
- The Ovulation phase: The ovulation phase is a time before and after ovulation. The mature ovarian follicle ruptures and discharges an egg or ovum. The woman could get pregnant when she is ovulating.
- The Luteal phase: The luteal phase is thepost-ovulation phase. Here the corpus luteum is created which is a temporary endrocine structure that produces oestrogen or progestogen. To protect the inner membrane of the uterus the body requires oestrogen and progestogen.
However, the safe days also depends upon the lifespan of both the egg and the sperm. If the menstrual cycle is of 28 days then ovulation may occur in the 14th day of menstrual cycle. The ovulation time is sometimes different for different woman as it may occur from the 12th to 19th day of the cycle. The sperm lives for 3 to 5 days so if you have unprotected sex 5 days before ovulation you may become pregnant. The egg has a short lifespan of 24 hours and if fertilisation does not occur within that time then the egg will die. The calculation sometimes may be incorrect due to fluctuating hormones as most of the woman believes that it is safe to have sex after period starts or before it begins.
