Pregnancy conception calculator

Menstruation: The cycle begins with menstruation, where the uterine lining sheds and bleeding occurs. This phase typically lasts around 3 to 7 days.

Follicular phase: During this phase, one follicle becomes dominant and continues to mature, while the others regress. The follicular phase typically lasts around 10 to 16 days.

Ovulation: Ovulation is the pivotal phase of conception. Ovulation generally occurs around 14 days before the start of the next menstrual period, but it can vary among individuals.

Luteal phase: Following ovulation, the luteal phase begins. This phase prepares the uterus for the potential implantation of a fertilised egg. The luteal phase typically lasts around 12 to 16 days. 

First Day of Last Menstrual Period (LMP): The LMP is used as a reference point because it is typically easier to recall than the exact date of conception. Calculators estimate when ovulation and conception may have occurred based on this information.

Average Length of Menstrual Cycle: Calculators use the average cycle length to estimate when ovulation is likely to happen.

Ovulation Timing: Ovulation is when the egg is released, and it's crucial for conception. Calculators assume it occurs around the middle of the menstrual cycle to estimate the fertile window.

Sperm Lifespan: Sperm can survive in the reproductive system for a few days. Including this factor widens the estimated conception window to cover the days around ovulation.

Average Gestational Period: The due date is calculated by adding around 40 weeks to the estimated conception date. This is based on the average length of pregnancy, but individual pregnancies may vary.

Calculators provide an estimated date of conception, helping individuals track when they likely became pregnant.

Calculators can estimate the due date by adding the average gestational period to the conception date.

They provide information about the menstrual cycle, ovulation, and fertility, increasing understanding of reproductive health.

Easily accessible online or through apps, calculators offer a convenient way to estimate conception and due dates.

Calculators provide reassurance and a sense of direction for those trying to conceive.

Track your menstrual cycle. This will help you to determine your average cycle length and ovulation date. You can track your menstrual cycle by using a period-tracking app or by keeping a calendar.

Take your basal body temperature. Basal body temperature rises slightly after ovulation, so taking your temperature every morning can help you to pinpoint your ovulation date. You can take your basal body temperature using a basal body thermometer.

Use an ovulation predictor kit. Ovulation predictor kits assist in measuring the level of luteinizing hormone (LH) in your urine. LH levels surge just before ovulation, so using an ovulation predictor kit can help you to identify your most fertile days. You can buy ovulation predictor kits at most drugstores.

Have intercourse regularly during your fertile window. Having unprotected intercourse during this time will increase your chances of conception.
