Ovulation Date Calculator – Forbes Health

Enter the first day of your last period and your cycle’s typical length. Our calculator will then provide your expected ovulation date and the range of days when you are most fertile.

Note: Many people have variable cycle lengths that change from month to month. Experts recommend assessing your average cycle length over the course of three months before calculating your fertile window.

Ovulation is when an adult ovum moves through the fallopian tube to be fertilized by sperm. The uterine lining thickens during the preovulatory phase in anticipation of a possible pregnancy, which prepares the uterus for a fertilized egg.

Ovulation occurs at the end of the follicular phase, which begins on the first day of your menstrual period and ends with ovulation. If the egg is not fertilized, the uterine lining is shaken during the part of the cycle known as menstruation.

When do you ovulate?

Most people ovulate anywhere between day 10 and 17 of their cycle, which is counted from the first day of your last menstrual period. However, ovulation dates can vary from one cycle to the next, and ovulation can even occur even in the absence of a menstrual period. If you are monitoring your cycle and using an ovulation computer, you can give a clear understanding of your ovulation schedule when trying to conceive.

Signs and symptoms of ovulation may vary from person to person, and some may not experience any symptoms. The primary signs used to predict ovulation include:

• Changes in cervical fluid
• Changes in basal body temperature
• Changes in cervical position or firmness

Some people also experience secondary symptoms of ovulation, including:

• Cramps or pain on one side of the lower abdomen
• Soft breasts
• Inflate
• Light stains
• Increased sex drive
• Increased senses of smell, taste or vision

Regular sex on your fertile days, which includes five days before and the day of ovulation, can increase the chances of getting pregnant in a given month.

If you are trying to conceive, the American College of Obstetricians and Gynecologists (ACOG) recommends having sex on your fertile days, preferably every day or every other day. Maintaining a healthy weight can also help increase the chances of pregnancy, as being overweight or underweight can increase the risk of complications.

Use our ovulation tracker in conjunction with detecting your own symptoms to determine which days of your cycle you are fertile. Consider tracking and mapping your basal body temperature and also monitoring changes in your cervical mucus, for added accuracy. To increase the chances of pregnancy, avoid alcohol, smoking and consider limiting caffeine.

For additional information and help, discuss your pregnancy plans with your healthcare provider so that they can assess any current medications you are taking that may interfere with fertility. Your doctor may also advise you on other lifestyle changes that may improve your chances of getting pregnant.
