What are the chances of pregnancy depending on the day of the month?

 The chances of pregnancy increase considerably as the considered "fertile window" approaches, and decrease little by little as the woman ovulates and fertilization does not occur. If we take into account that fertility increases and decreases each month, what are the chances of getting pregnant depending on the day of the month we are on?

There is no doubt that when sexual intercourse coincides with the most fertile days of ovulation, the chances of conceiving increase considerably. It is necessary to know each phase of the cycle to try to get pregnant faster. In fact, when you're trying to conceive, you may very well feel like everyone around you is getting pregnant without even trying.

However, from the moment the decision is made to get pregnant, conception  seems to never come, and months and months can pass before finally having the long-awaited positive pregnancy test. Even if you know of cases in which pregnancy occurred quickly (even in the following month after stopping the contraceptive pill), it is essential to know that most couples do not get pregnant the first time , or in one go.

It is estimated that the chances of conceiving in each cycle are between 25 to 30 percent if you are under 35 years of age, and 8 to 15 percent when you are between 40 to 42 years of age. These figures drop to 5 percent when you are 43 years old. Furthermore, it is essential to keep in mind that age not only affects fertility rates, but also spontaneous abortion rates , which increase from around 10 percent at the age of 20, to 15 percent after the age of 20. 35 years, and up to 50 percent from 45 years of age.

When it comes to maximizing the chances of conception, many experts agree that it is worth monitoring ovulation . And as reported in a study published in 2003 in the journal Human Reproduction , when the participating women (a total of 346 women between 20 and 44 years of age) followed their ovulation, they had a 38 percent chance of of conceiving in one cycle, a 68 percent chance in three cycles, an 81 percent chance in six cycles, and up to a 92 percent chance of achieving pregnancy within 12 cycles.

What are the chances of getting pregnant during your period?

Menstruation basically consists of the shedding of the endometrium , the  inner membrane of the uterus, which tends to occur every month. For most women, this lasts approximately three to seven days. By the third day, both progesterone and estrogen levels increase, and are working to rebuild the endometrium.

By the fourth day, the maturation of the follicles begins to increase, which means that the ovaries are beginning to prepare eggs for release. Unless you ovulate very early (we must keep in mind that the average time for ovulation is 14 days before the start of your period), the chances of conceiving at this time are almost zero .

What are the chances of getting pregnant immediately after menstruation?

Most experts agree that they should have sexual relations frequently, two or three times a week, but every two days , shortly after stopping menstruation, in order to cover, thereby, the so-called pre-ovulation window.

This is because, around day seven of the cycle, it is common to notice vaginal discharge that feels a little stretchy to the touch . In a few days it will turn white and acquire a creamy texture. This will be the sign that fertility is returning again. But it does not mean that the egg has been released yet, but it does become an excellent indicator that ovulation is on the way , and a sign that the cervical mucus has become a much friendlier environment for sperm.

We must remember that pregnancy is possible immediately after your period, even if you are not ovulating. Because? Mainly because sperm can live up to a maximum of five days when they are trapped in fertile cervical mucus .

The chances of conceiving at this time are good. Although it is true that an egg could not be released yet during this stage, it is appropriate to have sexual relations in case ovulation occurs earlier than planned.

What are the chances of getting pregnant during ovulation?

Indeed, we are at the best time for conception . Regardless of how long your periods may be, ovulation usually begins about 14 days before your next period . And, when this happens, the body temperature tends to increase by about half a degree. However, it must be taken into account that this usually occurs when you have already ovulated, so it could end up being too late.

It is precisely at this time when ovulation kits can be very helpful, given that when the tests are positive, it is advisable to have unprotected sexual relations in the next 24 to 36 hours.

The change in the consistency of cervical mucus also becomes another good indication of fertility. Vaginal discharge may increase in quantity, and will acquire a consistency similar to egg white (it should be thin and spread easily between the fingers). This will be a clear sign that it is the perfect time to have sex.

And after ovulation? What are the chances of pregnancy?

Also known as the luteal phase , it consists of the final part of the cycle, which lasts a minimum of 12 days, and a maximum of 16. At this time, progesterone begins to increase, which is a sign that the ovaries no longer need release more eggs this month. Additionally, the cervical mucus will begin to dry out, creating a plug to prevent more sperm from entering the uterus.

The chances of conception are equally low in this case.
