What Is The Difference Between Ovulation Days And Fertile Days

  • As previously mentioned, an egg can survive for up to 24 hours, while sperm can remain active for as much as five days. That means you can get pregnant if you have sex somewhere around four to five days before the egg release. So, the fertility window is about six days in which you can conceive. If you have unprotected sexual intercourse, of course. The chances of getting pregnant outside of this fertility window are pretty low.

  • Knowing the exact days when you are most likely to get pregnant gives you more opportunities to plan sex with your partner. This flexibility will significantly reduce the pressure you might be feeling.

The Ovulation Cycle Divided Into Two Parts:

  • The first part of the cycle is called the follicular phase. This phase starts the first day of the last menstrual period and continues until ovulation.

This first half of the cycle can differ greatly for each woman lasting anywhere from 7 days to 40 days.

  • The second half of the cycle is called the luteal phase and is from the day of ovulation until the next period begins. The luteal phase has a more precise timeline and usually is only 12-16 days from the day of ovulation.

This ultimately means that the day of ovulation will determine how long your cycle is. This also means that outside factors like stress, illness, and disruption of normal routine can throw off your cycle which then results in changing the time your period will come. So the old thought that stress can affect your period is only partly true. Stress can affect your ovulation which ultimately determines when your period will come, but stress around the time of an expected period will not make it lateit was already determined when it would come 12-16 days earlier!

Fertility Awareness is one way to track when ovulation occurs, and it includes noticing the changes in cervical mucus and using a basal thermometer. Cervical fluid will change to a wet, slippery substance that resembles egg whites just before ovulation occurs and until it is over. A basal thermometer helps track a body temperature rise, which signals that ovulation has just occurred.

When Do Women Ovulate

It would be great if you could track your ovulation days like regular days of the week. However, not every woman has the same ovulation period because cycles can vary. Generally, however, ovulation occurs in the middle of your menstrual cycle.

Therefore, in a typical 28-day menstrual cycle, ovulation will occur somewhere around the 14th day. Since its impossible for every womans ovulation period to fall in a narrow timeframe, lets just say that it can happen four days before or after the midpoint of your cycle. This highlights a period thats about one week long, which you should track carefully if you want to get pregnant.

From The Menstrual Period To Ovulation

When your menstrual cycle begins, your estrogen levels are low. Your hypothalamus sends out a message to your pituitary gland which then sends out the follicle stimulating hormone . This FSH triggers a few of your follicles to develop into mature eggs. One of these will develop into the dominant follicle, which will release a mature egg and the others will disintegrate.

As the follicles mature they send out another hormone, estrogen. The high levels of estrogen will tell the hypothalamus and pituitary gland that there is a mature egg. A luteinizing hormone is then released, referred to as your LH surge. The LH surge causes the egg to burst through the ovary wall within 24-36 hours and begin its journey down the fallopian tube for fertilization.Ovulation Predictor Kits work by detecting this LH surge. The follicle from which the egg was released is called the corpus luteum, and it will release progesterone that helps thicken and prepare the uterine lining for implantation. The corpus luteum will produce progesterone for about 12-16 days

If an egg is fertilized, the corpus luteum will continue to produce progesterone for a developing pregnancy until the placenta takes over. You can begin looking for pregnancy symptoms as early as a week after fertilization. You can also begin testing for pregnancy as early as 7-10 days past your ovulation date with an Early Detection Pregnancy Test.

What Is The Fertile Period

The fertile period is the time of the menstrual cycle when there is the greatest chance of pregnancy. In a normal 28-day cycle, ovulation is expected to occur 14 days after the start of menstruation. Some women may experience pain on the day of ovulation. The body temperature can also rise a little, around 0.5 ºC. Also a little bit of pain can be felt when the ovary releases the egg. Often the woman may notice a mucous discharge on the first day after ovulation, similar to an egg white. Libido can also increase during the fertile period.

Fertile days are usually 6 days . The period ranges from about 5 days before ovulation to one day after ovulation. However the greatest chance of pregnancy is about one to two days before ovulation until the day of ovulation.

But the tablet is not an effective contraceptive method. Without complementary exams it is not possible to be sure. Therefore, our fertility table should not be used as a contraceptive method .

Things To Know About Ovulation

As we mentioned in the paragraph above, theres actually only a small window of opportunity each cycle for making a baby just a few days in fact. The day of ovulation is usually the most likely date for conception but it is possible if you try a few days before ovulation too. Thats because the sperm can live for a few days and wait for the egg to get to the fallopian tubes.

Trying for a baby is a great excuse to have frequent sex. Youre most likely to conceive if you have sex in the days around when the egg is released, but trying every two or three days throughout the month is worth a go. Even if it just takes the pressure off and makes things feel less regimented.

Besides tracking her cycle, a woman can also calculate ovulation date with other methods.

Ovulation Predictor Kits : The most accurate way to know when you’re ovulating is to use an ovulation predictor kit . These work by detecting a surge in luteinizing hormone , which your body releases up to two days before you ovulate. Because these kits give you the most advance warning, they’re your best bet for knowing when to time sex to coincide with ovulation.

Basal Body Temperature: Your basal body temperature increases slightlyabout half a degree when ovulation occurs. Because this spike is so small, you need a special basal body thermometer to measure it.

Vaginal Discharge: Your vaginal discharge can help predict your ovulation date as well. Most women have a clear and somewhat elastic discharge in the days leading up to ovulation.

Ovulation Symptoms: Some physical symptoms may accompany ovulation, but they’re subtle enough that not everyone can spot them. About 20 percent of women experience lower abdominal pain when ovulation occurs. Breast tenderness is also common.

Doctor Visit: With blood tests and pelvic ultrasounds, doctors are able to monitor your ovulation cycle, says Jingwen Hou, M.D., Ph.D., an Ob-Gyn specializing in reproductive endocrinology and infertility at Kaiser Permanente in Hawaii.

How Does The Menstrual Cycle Work

  • Your cycle starts on the first day of your period and continues up to the first day of your next period.
  • At the same time, eggs begin to mature in the ovary.
  • The lining of the womb thickens ready for fertilisation.
  • During ovulation your cervical mucus becomes thinner and clearer to help the sperm reach the released egg.
  • About 10 to 16 days before the start of your next period, an egg is released from one of the ovaries .
  • If sperm is present at the moment of ovulation, or some time during the next 24 hours, the egg may be fertilised.
  • If the egg has not been fertilised, the egg is re-absorbed by the body, the hormone levels drop, and the womb lining is shed. This is the beginning of your next period.
