The liberation of the egg that got ripe in the fallopian tube after releasing from the ovary is known as ovulation. Ovulation always occurs once a month. LMP is defined as the last menstrual period. It is nothing but the time when your menstrual period has lasted when you become pregnant. It is used by the doctor to tell at which date you are going to expect your child. Basically, it is told that it can be after 40 weeks or sometimes a little time before 40 weeks from LMP.

Before falling pregnant it is the first day when periods have ended or the day at which your menstruation lasts. Remember that ovulation always occurs before your periods start as it makes the egg so much time is needed hence after a certain time your periods start.

Ovulation mainly occurs for one time in a whole month. It basically occurs for up to 10 days. The timings of ovulation can vary depending upon the menstrual cycle and how regular it is. Many people get ovulated from eleven to twenty-one days, any day among these. Remember it is not necessary that ovulation occurs on the same day or date. These can vary from that which was expected either sooner or later. In a pregnant woman, ovulation starts after forty-five to ninety days when they have given birth to the child.

To calculate the time for ovulation you have to start from the first day of LMP. Or you can also calculate it by taking approximately twelve to fifteen days from the succeeding expected period. Many people have the same time period for ovulation but there are few women who ovulate within a week or even after their last period. So, some have an exceptionally short cycle of ovulation. This is a natural thing for them.
