The fertile calendar will let you know when your fertile days are and when you cannot fertilize. The ovulation calendar is a useful tool for both women planning a baby and those who want to avoid pregnancy.

Use a calculator and calculate your fertile days!

How to calculate fertile days with fertile day calendar? All you need to do is enter two pieces of information: enter the date of your last menstruation - NOTE! you should enter the first day of your last period - and the average length of your menstrual cycle.

Remember that while the fertile days calendar will help you show your fertile and infertile days, it cannot be considered one of the methods of contraception. It is most effective in the case of regularly menstruating women, although in them, the length of the menstrual cycle is influenced by various factors, including he alth, stress, climate change.

When are the fertile days?

Fertile days occur in the middle of the menstrual cycle - on average it lasts 28 days, so ovulation falls on the 14th day of the cycle. A woman has a good chance of becoming pregnant also up to 4 days before and the day after ovulation, but fertilization is possible up to a week before ovulation.

The female egg only lives for 12 hours, but the longer life span of sperm cells - up to 5-7 days - allows them to remain in the woman's reproductive tract for this time and thus extend the period of fertility. Our fertile days calendar takes this factor into account, so it tells you the 8 fertile days you can become pregnant.

How do I recognize my fertile days?

The use of the fertile days calculator should be accompanied by careful observation of the body. A woman can tell when her fertile days are if her body temperature has risen by 0.2-0.6 degrees Celsius - it stays there overnight and indicates ovulation.

The fertile days are also accompanied by clear, stretchy and sticky vaginal mucus. Some women also observe an increase in libido, experience pain in the lower abdomen near the ovary and develop breast tenderness. In some women, the fertile days are asymptomatic.
