When can I get pregnant?

The ovule can only be fertilized, for a few hours, after ovulation. So it is not possible to get pregnant during the 8 days from the beginning of menstruation, or in the 8 days before the next menstruation.


What are the fertile days?

Knowing what are the fertile days of the woman, is the most important thing to know when to have sex. To estimate when you can get pregnant you have to calculate the days of ovulation, taking into account that it happens about 14 days before the next menstruation.

When does ovulation occur?

The menstrual cycle begins with bleeding, the first day of the cycle is the first day of menstruation and the last day of the cycle is the day before menstruation. The whole cycle lasts approximately 28 days.

Ovulation occurs about fourteen days before the period. Therefore, the fertile days of the woman with cycles of 30 days would be close to the 16th day of the menstrual cycle.

Ovulation symptoms

The vaginal discharge becomes more viscous (the mucus is more abundant, thick, clear, and more easily spread). It is more frequent to feel more desire to have sex and to dress provocatively.

If you had sex during the fertile days, without protection and you do not want to get pregnant you should take the pill the next day (Postinor) although its effectiveness is not as good as the condom, the IUD, the contraceptive pills or the contraceptive implants. You must also take care of sexually transmitted infections (such as HPV)
