This means you can get pregnant from intercourse that occurred either just before or just after ovulation. If the egg is not fertilized, the lining of the uterus, which has thickened to prepare for fertilization, sheds through menstruation. The first day of heavy flow marks the first day of your next cycle, and the process begins again.

Ovulation basics When you ovulate, a mature egg is released from the ovary and moves into the fallopian tubes, where it is available to be fertilized. When Does Ovulation Occur? When ovulating or approaching ovulation, the body produces more estrogen, causing an increase in cervical fluid secretion.
When a person is fertile, the cervical fluid in their vagina may be:. This type of cervical fluid helps sperm swim into the uterus and fallopian tubes to fertilize the released egg. If the fluid is stringy, the person may be close to ovulation. After ovulation, there is less cervical fluid and it thickens.
Basal body temperature BBT is the temperature of the body at rest. For the most accurate reading, a person should take it as soon as they wake up. During ovulation, this temperature may slightly increase as the body secretes progesterone, a hormone that helps thicken the uterine lining in preparation for the implantation of an embryo.
Because the increase is so slight, around 0. People are at their most fertile 2—3 days before their BBT is at its highest point and 12—24 hours after ovulation. Because BBT only rises after ovulation, people may prefer other ways of checking their fertility, such as tests that measure levels of luteinizing hormone LH in urine. Some people have a higher sex drive during ovulation. Increased libido tends to coincide with the rise in estrogen and the production of LH that causes the ovaries to release eggs.
Research suggests that the increase in sexual desire may begin 3 days before LH levels peak and last for around 6 days. Breast or nipple soreness or tenderness may be mild to severe during ovulation or when it approaches.
Higher levels of estrogen and LH can cause breast pain in some people just before ovulation. After ovulation, however, the decrease in estrogen and increase in progesterone can also trigger breast and nipple tenderness. Some people feel lower abdominal pain on one side during ovulation. This is known as ovulation pain, or mittelschmerz, and it typically occurs on the ovulating side. It often happens as LH levels peak, when the follicle containing the egg to be released is developing but has not yet ruptured.
The pain typically stops within 3—12 hours. The window refers to the days in a cycle when pregnancy is possible. Its duration can vary, depending on the length of the cycle. 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.
