When are you most fertile? Discover your cycle!

 

Daysy lets you know every day whether you are currently fertile.

A woman's cycle is fascinating as it serves to conceive a child and bring forth the miracle of pregnancy. Every individual cycle is a little bit different and differences between two distinct women can be substantial. And yet there are commonalities that enable the determination of the fertile days. If you find yourself asking „When is a women fertile?“, you should read on.

When am I fertile? Your 6 fertile days

Nature enables us to become pregnant on three to six days of the cycle, although the female egg can only be fertilised during a period of approximately 12 to 18 hours. This period is created because the male sperm can wait for the egg for several days. If sexual intercourse takes place a few days before ovulation, the sperm swim into your fallopian tubes and wait there. When, during ovulation, the egg „jumps“ into the tubes, the sperm are ready to receive it and, if possible, fertilise it.

Due to this scientific fact, we end up with a fertile period of usually six days per cycle. For some men, sperm are not active that long, which us why the time frame can be slightly shorter. In any case, the day of ovulation remains highly fertile, even when sperm are only active for a very short time. But such cases are very, very rare.
