Planning to experience motherhood? Before you plan for this exciting and beautiful journey, it is important that you have the right information regarding your ovulation cycle. This will help you to decide when you can try for conception, thereby, increasing your chances of getting pregnant.

What Is Ovulation?

Ovulation is a crucial stage in the female menstrual cycle during which a developed egg is released from one of the ovaries. It occurs around 14th day of a typical 28-day menstrual cycle. This marks the fertility window, i.e. when the woman has higher chances of getting pregnant.

There are several signs of ovulation, such as:

  • Increase in basal body temperature
  • Cervical mucus turns clear and slippery
  • Tenderness in breast
  • Mild cramps in the abdomen
  • Heightened sensitivity to smell
  • Increased sex drive
  • Changes in mood and appetite
  • Bloating

How to Calculate Your Ovulation

With the help of Ovulation Cycle Calculator, you can predict when you might ovulate and thereby boost your chances of getting pregnant. It estimates your ovulation date by counting back 14 days from the day you expect your next period. Suppose if your menstrual cycle is 28 days long, then your next period should start 28 days from the first day of your last period.

What Is the Fertile Window?

Fertility Window includes the ovulation day and five days before this day. It is important to note that you are more likely to conceive if you have intercourse during the fertility window.
