How Many Days After Period Is Safe To Avoid Pregnancy

If you are planning to get pregnant, you should practice sex without contraception. A woman is more likely to conceive during the fertile window stage of the menstrual cycle, known as the ovulation phase.

Ovulation is a phenomenon when ovaries release the mature egg towards the fallopian tube .

If you have a regular menstrual cycle, you are more likely to get pregnant during the 10th-14th day, considering the onset of menstruation as day 1. However, the days can vary among each woman.

Sperms can survive in the woman’s body for 5-7 days. Thus if you have intercourse without contraception during the fertile window of the menstruation cycle, you are more likely to get pregnant.

What Is The Menstrual Cycle

The menstrual cycle is what your body goes through to get ready for pregnancy. This cycle is the time from the first day of your period up to the day before the start of your next period.

Ovulation usually happens during the second half of the cycle. This is when an egg is released from one of your ovaries. To get pregnant, the egg needs to be fertilised by the sperm.

Ovulation doesnt happen every month for every woman. There are some conditions that may interfere with ovulation, such as endometriosis and polycystic ovarian syndrome . If you are not getting a monthly period and are trying to get pregnant, speak to your doctor.

Why Should You Calculate Your Safe Period

However, more importantly, safe period calculation is a great method of birth control because it does not involve ingesting hormonal birth control pills, using an IUD, or hormone injections which can have different effects on different women, ranging from extreme mood swings to weight gain and other problems that hamper ones well-being.

When Does Ovulation Happen

Safe Period Calculator to Avoid Pregnancy

It’s difficult to pinpoint exactly when ovulation happens, unless you’re practising fertility awareness . However, ovulation usually happens 10-16 days before the start of a woman’s next period.

The menstrual cycle is counted from the first day of a womans period. This is day one. Some time after her period she will ovulate, then 10-16 days after this she will have her next period. The average cycle takes 28 days, but shorter or longer cycles are normal.

Its not accurate to say that women are fertile on day 14 of the menstrual cycle, says Toni Belfield, a specialist in sexual health information and a trained fertility awareness teacher. Being fertile on day 14 might be true for women who have a regular 28-day cycle, but it wont apply to all women.

If your cycle is 35 days long, you’re not going to be fertile on day 14 of your cycle. Youre more likely to be fertile around days 19 to 25. If you have a shorter cycle for example, 23 days you might ovulate around days 7 to 13.”

Sperm can survive in a woman’s body for several days after sex. If you want to get pregnant, having sex every couple of days will mean there are always sperm waiting in the fallopian tubes to meet the egg when it’s released.

This calculation is adjusted to reflect WHO data showing that approximately 80 percent of menstrual cycles range between 26 to 32 days. The ovulation period varies from woman to woman. It can happen anywhere from the 12th to the 19th day of the menstrual cycle.

  • The sperm can live in your reproductive system for up to five days. That means it is possible to conceive from unprotected sex if you had it five days before ovulation, even though the lifespan of a viable egg is only approximately 24 hours. If it’s not fertilized in 24 hours, it will die, and it will be safe for you to have sex.

Contraception Methods During Safe Period
