How many days after menstruation can I get pregnant?

Your body is made up of cycles. To get pregnant, you need to find the right time in the cycle to increase your chances of conception. You therefore need to determine the number of days after your period to get pregnant. Let’s take a look at the course of a cycle to better understand how ovulation and conception occur, and the life span of sperm, using concrete examples.


Le déroulement du cycle

To get pregnant, the starting point is your menstrual cycle. In theory, it begins on the first day of menstruation and lasts an average of 28 days.

As for the menstrual period, it lasts 5 days on average ( plus or minus 2 days).

Ovulation occurs between the 12th and 16th day of the cycle.


Then comes the key moment of fertility: ovulation. It’s the precise moment when the ovary releases the egg. A new egg is being formed during your period. It will grow until it is released during the next cycle, which begins with the first day of your period.

But the maturation time of the egg is very variable. It is thus extremely difficult to accurately predict the date of ovulation and it can easily vary by a few days.

Furthermore, you should know that the egg has a maximum lifespan of 24 to 48 hours. This limits the fertility period.


Conception is the moment when the sperm meets the egg in the fallopian tube and manages to fertilize it.

For this to happen, all the necessary conditions must be met: the sperm must be present around the time the egg is released from the ovary. This may be before ovulation or simultaneously. Depending on the timing, you will increase your chances of having a boy or a girl. Aiming for the right timing to influence the sex of your future baby is what the MyBuBelly method offers by giving you all the keys to identify your ovulation and the right diet.


Sperm life span

The lifespan of sperm is estimated at 2 to 3 days in the fallopian tube.

Therefore, if they are present up to 3 days before the egg is expelled from the ovary, conception has a high probability of occurring. This timing will also increase your chances of having a baby boy.

In short, every woman is different and has her own cycle. You can very well get pregnant three days after the end of your period (more frequent for a short cycle), 10 days later (if you have an average cycle) or 15 days later (if you have a cycle of more than 30 days). What is important is to determine when you ovulate. MyBuBelly helps you to recognize it and assists you in finding the best time to conceive, as well as helping you to fulfil your dream of having a girl or a boy.
