Although science has discovered that most women have a 28-day cycle with ovulation on day 14, women's bodies don't care what the research says.

If a woman has never tracked her ovulation by using tracking her basal body temperature or ovulation predictors, she might not realize that her cycle is just a little bit different.

There are also many things that can happen during the month to affect a woman's ovulation date.

Illness, stress, exercise, and medications that contain hormones all play a factor in ovulation, which can also influence a woman's probable date of conception if she conceives during this time.

A woman using ovulation predictors who is tracking her cycle might know that she is going to ovulate on the 14th and plan intercourse for the same day.

This extra information, however, is confusing to some moms who thought they knew when they conceived based on their ovulation date.

As long as the date the doctor estimates for conception is within a week or so of ovulation, there really isn't anything to be concerned about.

The key to determining when to try to conceive is ovulation.

Healthy women in their childbearing years typically follow the cycle each month and ovulation is a key component to the cycle.

During ovulation, the egg is released from the ovary and it travels into the uterus through the fallopian tube.

Tracking your cycles on an ovulation calendar requires some patience but it can help you find the best time to conceive.

An ovulation predictor kit is the most technical of the strategies and it can improve your chances of conceiving.

The predictor kits and fertility monitors work by testing urine for a spike in specific hormones associated with ovulation.

Track your menstrual cycle with an ovulation calendar to know which days of the month you are most fertile and make sure that your partner also has this information and knows why it's important.

Hormonal IUDs are designed to interfere with the sperm's movement and to reduce ovulation by releasing progestogen.

An important consideration is your time of ovulation.

Make sure to avoid intercourse before having the device removed if you are close to ovulation and use alternative birth control after removal.

When a woman is infertile the causes may be traced back to problems with ovulation, lifestyle or physical malformations.

Ovulation is the process where the egg leaves the ovary and travels down the fallopian tube to be fertilized by the sperm.

A woman may begin ovulation as early as two weeks after an abortion, but you may not get your period until four to six weeks after the procedure.

On the first day of your menstrual cycle (that is, the day you first start your period) the process begins to start ovulation, the releasing of the egg from the ovaries.

This process, known as ovulation, usually occurs at day 11 or 16 of the monthly cycle, that is, 11 to 16 days after the beginning of the last period.

The time period of ovulation is different for each woman and may change if a woman is stressed, sick, or has changes in sleep patterns.

If it does not contact sperm, either from intercourse that happened before ovulation or in the 12-24 hours after ovulation, it will die and be reabsorbed into the uterine lining.

Within these generally fertile times, you are most likely to conceive if you have intercourse between 48 hours before and 24 hours after ovulation.

The presence of these signs can be a good general predictor of ovulation timing, but to determine exactly when you are ovulating, it's best to use one of the commercially available ovulation predictors.

These tests predict ovulation up to 98 percent accurately with a simple urine test.

If you are serious about conceiving this year, consider using a pregnancy and ovulation calendar to help determine the most fertile days of your menstrual cycle.

Every woman's cycle is different, so these types of calendars are helpful in pinpointing specific target conception dates, as well as teaching you how to look for and track particular physical signs of ovulation.

When your ovaries release a fertile egg during ovulation, it is typically only available to be fertilized for about one day, or around 12 to 24 hours.

This may lead some people to believe that their ovulation window consists of only one day a month.

The pregnancy and ovulation calendar takes several components into consideration to predict your ideal fertilization window.

When a woman has a 28-day menstrual cycle, ovulation usually happens around day 14 of the cycle.

However, many women do not have consistent 28-day cycles, which can then change their ovulation dates and conception window periods.

Cervical fluid changes consistency throughout your monthly cycle, which can help you predict your ovulation window.

For example, when you are approaching your ovulation window, you should be able to see an increase of white cervical fluid.

During actual ovulation, this fluid increases and becomes slippery, sticky, and stretchy.

After ovulation, the amount of moisture will decrease.

The basal body temperature, or your body's natural temperature when you are resting, is another important component of the ovulation calendar.

Most people's body temperatures increase during ovulation.

In order to create the most accurate and effective ovulation calculator to predict the best time for conception, you can track the main calendar components and utilize several popular tools as well.

Some women use free online ovulation calculators to help estimate which days they are most fertile.

From the time your period begins until ovulation, your temperature will vary between 97.2 degrees F and 97.6 degrees F, but from the time of ovulation until your next period begins, your BBT will typically raise as much as one degree.

The medication causes ovulation occur about 40 hours after having the injection with egg collection taking place about 34 hours after the injection to ensure that the eggs are ready, but that ovulation has not occurred yet.

Because pinpointing the exact moment of ovulation is difficult, women should use other methods of checking ovulation beyond any physical signs and symptoms, especially if they are using natural family planning birth control.

Although men can carry the gene for hyper ovulation and pass it on to their daughters, a history of twins on the man's side of the family doesn't make a woman any more likely to give birth to twins when she becomes pregnant.
