Understanding Your Cycle

A typical menstrual cycle lasts around 28 days, but it varies from woman to woman. Knowing your cycle length helps you estimate your ovulation day, when you're most likely to conceive. Irregular cycles can make it more challenging, but not impossible. You might find our article on irregular period conception helpful.

The Fertile Window

Your fertile window includes the days leading up to ovulation, the day of ovulation, and the day after. Sperm can survive for several days in the female reproductive tract, so having intercourse a few days before ovulation can also lead to pregnancy. You can learn more about this in our article fertile window after period.

Factors Affecting Conception

Many factors can influence conception, including age, overall health, and lifestyle. Understanding these factors can help you optimize your chances of getting pregnant.

Confirming Pregnancy

The best way to confirm pregnancy is with a home pregnancy test or a visit to your doctor. Home pregnancy tests detect the presence of hCG (human chorionic gonadotropin) in your urine, a hormone produced during pregnancy. If you ovulated on the 16th of the month, you can use the information on our page about when to test: when to test.
