A fertility calendar can help women track their menstrual cycles for both birth control and fertility purposes. It takes into account that every woman’s cycle is unique and can predict when a woman is most fertile. Basal body temperature tracking can provide a more accurate prediction of ovulation.
A fertility calendar is a way for women to track their monthly cycles. It can be used as both a birth control method and a fertility method. Learning to use and read a fertility calendar is easy. By inputting a few numbers, you can create a fairly accurate calendar of a woman’s fertile days.
Also called the rhythm method, fertility calendars are designed around a woman’s personal monthly schedule. It takes into account that every woman’s cycle is unique. For example, a woman’s cycle length averages twenty-eight days. However, it can last up to ten days or up to sixty days. Some cycle lengths vary from month to month.
Fertility calendars help track and measure the length of a cycle. For a woman trying to conceive, it is important to know when she is ovulating. This is equally important for a woman who is trying not to get pregnant. By tracking the first day of her period for a couple of months, a woman should be able to see a pattern of her monthly cycle.
Using the length of her cycles and the first day of her most recent cycle, a fertility calendar can tell a woman when she will be most fertile. Some charts can even predict when the best time will be to reach out to a guy or girl. Sperm Y (male) moves faster than sperm X (female). However, X sperm live longer. So having intercourse a few days earlier will be more likely to result in a girl, because the Y sperm will be dead by the time the egg is released. Waiting a few days for intercourse, up to a day before ovulation, will give the fastest Y sperm a better chance of reaching the egg first. Abstaining from sex during the fertile window will prevent a woman from becoming pregnant.
A fertility calendar can also tell a woman when her next expected period is, as well as when to test for pregnancy. They can even tell when the baby will be born, based on the estimated date of conception. Fertility calendars have helped millions of women conceive, but they aren’t perfect. They work on the assumption that women ovulate midway between their cycles, which isn’t always true.
A more accurate picture of when ovulation will occur is being gleaned by taking the idea of a fertility calendar one step further. By recording her cervical position, vaginal secretions and temperature, ovulation can be predicted more accurately. Because the female body changes in definite ways through the different phases of a woman’s cycle, it is possible to track a woman’s fertility. It’s called basal body temperature (BBT) tracking, and it’s recommended by many fertility doctors for couples who are having trouble conceiving.
With a fertility calendar, women are able to plan a pregnancy. Women who know when their fertility window is have a better chance of conceiving than a woman who is just guessing at the best time to have sex. Fertility calendars are an easy-to-use tool that all women should be familiar with.
