Hello Anonymous,

Welcome to EmpowHER. Understanding how reproduction happens is important.

Ovulation is when a mature egg is released from the ovary, pushed down the fallopian tube, and is available to be fertilized.

Approximately every month an egg will mature within one of your ovaries. As it reaches maturity, the egg is released by the ovary where it enters the fallopian tube to make its way towards waiting sperm and the uterus.

A woman’s monthly cycle is measured from the first day of her menstrual period until the first day of her next period.

On average, a woman’s cycle normally is between 28-32 days, but some women may have much shorter or much longer cycles.

Ovulation can be calculated by starting with the first day of the last menstrual period (LMP) 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.

Ovulation can occur at various times during a cycle, and may occur on a different day each month.

Pregnancy doesn't start the moment a penis ejaculates in a vagina. It can take up to six whole days for the sperm and egg to join and form a fertilized egg.

During these six days, sperm are hanging out in the reproductive organs, waiting for an egg to show up.

But since sperm swims through the vagina up to organs deep in your body, you can’t avoid pregnancy by trying to wash out the sperm. Once they’re in there, there’s no catching them.
Then, it takes another six to ten days for the fertilized egg to attach itself to the lining of the uterus. Pregnancy begins once all this happens. Planned Parenthood

I hope this is the information that you are looking for.

Thanks, Maryann. This has helped. Allow me to inconvenience you a little more. So how long does it take for postinor2 to delay ovulation and will it work if taken the third time if it has been taken as much as 3 times in a space of 4 months?( I know this usage is wrong. )

Hi Anonymous,

Postinor 2 is effective in preventing ovulation, if taken within 72 hours of unprotected intercourse and only if ovulation has not already happened.

It should only prevent ovulation once when taken but may cause a delay in ovulation the following month.

There isn't much information out there about taking the pill frequently. I do remember reading that if taken too frequently, as you have done, the effectiveness of the pill decreases.
