When is fertility period of a woman

If you wait until after the female has ovulated before you have sex, you will most likely have missed the opportunity for conception that month. Conception starts at the moment of fertilisation, when the sperm penetrates the outer shell of the egg, and an embryo is formed.

Over the next four to six days the embryo moves down the fallopian tube to the uterus, where it implants in the uterus lining and hopefully continues to grow. To check if you are pregnant, you should wait two weeks after ovulation before undertaking a pregnancy test. To calculate your Fertile Window, you need to determine what day you ovulate. To do this, you need to know the length of your menstrual cycle which tends to vary from 23 to 35 days. To calculate this — you should note how many days have passed from the first day of bleeding in your last period, to the first day of bleeding in your next.

From this figure, subtract 14 days from the end of your current cycle to determine the day you ovulate.

If you have irregular menstrual cycles, or your cycle length varies from month to month, it will be difficult to calculate your ovulation date. Ovulation urine tests may be useful, and you should consider seeking further advice from your GP or a Fertility Specialist.

There's no "safe" time of the month when you can have sex without contraception and not risk becoming pregnant. But there are times in your menstrual cycle when you're at your most fertile, and this is when you're most likely to conceive.

Your menstrual cycle begins on the first day of your period and continues up to the first day of your next period. After checking for several cycles, you may be able to see a pattern and identify your most fertile days. Catherino WH.
