Researchers discovered that most women have two waves of follicle development, but what does that mean for ovulation? Ovulation is the period of your menstrual cycle when an egg is released from an ovary. Each ovary contains million primordial follicles, each of which contains an egg. Some research has stated otherwise. In one study using daily ultrasounds, researchers discovered that 68 percent of women exhibited two waves of follicle development, even though they reported having regular menstrual cycles.
This means that the follicles that contain unreleased eggs mature and develop in some women twice in one month. These results may look promising for anyone struggling to get pregnant, but the truth is they are misleading. The body triggers the release of an egg from the ovaries. Once that egg starts its journey towards the uterus, it only stays viable for 1 day. However, sperm can live in the uterus and fallopian tubes, the tubes that connect the ovaries to the uterus, for up to 6 days.
This means that there are around 6 days of the menstrual cycle during which people can become pregnant. The body produces the highest amounts of the hormone estrogen during ovulation. This high surge of hormones causes the ovaries to release the egg into the fallopian tubes. The egg travels through them toward the uterus. Estrogen has already caused the uterus to thicken in preparation for implantation. These include :. Some people may experience the following signs and symptoms:.
People can usually only get pregnant if they are having unprotected sex just before or during ovulation. People are most likely to get pregnant if they have sex within a day or two of ovulation. However, it is possible for people to become pregnant if they have sex up to several days before ovulation because the sperm can swim up the fallopian tubes to wait for the ovaries to release the egg.
Fertility awareness methods , which people may also know as natural family planning or the rhythm method, may help people plan their sexual activity around their ovulation so that there is less of a chance they will get pregnant. However, a person who does not want to get pregnant should consider using birth control , which is much more effective at preventing pregnancy.
There are several ways in which people can track their ovulation to determine when they are at their most fertile:. In contrast, for individuals who do not wish to conceive, various methods of birth control are much more effective.
Some health conditions that may prevent ovulation include :. There are four stages of the menstrual cycle:. This phase typically occurs from days 0—14 of the menstrual cycle. If a person has a menstrual cycle that is not 28 days, it is because the follicular phase is either longer or shorter than 14 days. During this phase, the hormone that the body produces the most is estrogen. A person can use an ovulation calculator to determine their fertile window.
People are more likely to conceive if they have sexual intercourse from 5 days before ovulation to 1 day afterward. Generally, the closer to ovulation, the better the chances of conceiving. Once the ovary releases an egg, the egg dissolves within 24 hours if fertilization does not happen. Sperm can survive in the vagina for 3—5 days , which can influence when fertilization occurs. For people tracking their fertility at home, urinary LH kits tend to be the most reliable method.
Although fertility apps are growing in popularity, they are based on an algorithm and are not always accurate. Anyone who wants to prevent pregnancy should discuss other approaches with a healthcare professional. Sometimes, the signs of ovulation can instead stem from a health problem. For example, endometriosis can mimic ovulation pain. If any issues consistently arise halfway through a cycle, it might be a good idea to consult a doctor. If intense, lasting pain or vaginal bleeding occurs during ovulation, a person should receive medical attention as soon as possible.

During ovulation, an egg is only available to be fertilized for about hours. But sperm can live in the body for days after sex and the egg is available for one day, so your most fertile time is about days. This is a myth that many, including healthcare professionals, still believe.
This is not an accurate way to calculate ovulation because many women do NOT ovulate on the 14th day of their cycle. The day of ovulation differs from woman to woman and can even be different from month to month for an individual woman.
For a woman with a day cycle, the window of ovulation is day 11 through day 21 of your cycle. Ovulation could occur on any one day during this window. Menstruation or a period is the bleeding that occurs when the endometrium is shed 12 to 16 days after ovulation. With this definition of a period, you cannot ovulate while on your period. However, some women experience mid-cycle or ovulatory bleeding bleeding that occurs around ovulation and may mistake it for a period.
This can happen to women with very irregular cycles coming once every 3 months or times in one month. Mid-cycle bleeding can occur in women with regular cycles as well. They may experience what appears to be a period, but, in reality, this is most likely ovulatory bleeding. Ovulation can occur when you experience mid-cycle or ovulatory bleeding. Keep in mind that while you cannot technically ovulate while on a period because sperm can live in the body for days after sex, pregnancy could occur from intercourse that takes place during a period.
That is determined by how many days are in your cycle. The number of days in your cycle is calculated by counting the number of days from the beginning of one period to the beginning of the next period. If you have a short cycle, for example, 21 days, and you bleed for 7 days, then you could ovulate right after your period.
