How your fertile days are calculated?

It is vital for you to know that you cannot get pregnant on all days of the month. The fertility window is the period during which your chance of conceiving is high. You can know the fertile days by using the ovulation date calculator.

How to know your fertile days?

For this, you need to have a basic understanding of the menstrual cycle. During every menstrual cycle, the body starts preparing itself for pregnancy. Hormonal changes happen during this period and your ovary releases an egg which may get fertilized by sperm. The uterus lining thickens as part of preparing itself for implantation of the zygote (product of fertilization of egg and sperm). If you don’t conceive, the uterine lining sheds off resulting in periods.
