When is the chance of pregnancy high?

Although pregnancy is a random thing and cannot be expected, as the saying goes: everything is arranged by God. However, mothers who are preparing for pregnancy still hope to have their own babies, so they also make a lot of preparations before pregnancy. Therefore, we should also do some courses, such as: When is the chance of pregnancy higher?

When is the chance of pregnancy higher?

When is it easiest to get pregnant? Women are most likely to get pregnant during their ovulation period. If you have regular sex during your ovulation period, the chances of getting pregnant are relatively high. If you want to know when you are most likely to get pregnant, you must first understand the time of ovulation. The following are several reference methods to predict ovulation.

The first is the schedule calculation method. Generally speaking, women's menstrual cycle is 21-35 days (average 28 days), and ovulation is 12-16 days before the next menarche (average 14 days). The actual time can be calculated based on the schedule algorithm. The main method is to calculate the fertile and difficult periods in the current cycle based on the records of the past 12 or more menstrual cycles.

The second is the method of measuring body temperature during ovulation. The body temperature method is a relatively accurate way to measure the ovulation period, because generally speaking, a woman's body temperature will suddenly drop on the day of ovulation, and then the body temperature will rise by 0.3-0.5 degrees compared to the basic body temperature for a few days. Women who are preparing for pregnancy can buy a digital thermometer, set it below 35 degrees Celsius before going to bed every day, and measure their temperature immediately after waking up every day (after 8 hours of sleep) without doing any exercise. Because any posture may increase the body temperature and cause deviation, it is necessary to measure it without exercising. This should be continued for at least 14 days. It is best to persist in measuring it all the time, and record it and draw a trend chart to grasp the regularity of temperature rise and fall to determine your ovulation period.

The third is secretion observation. During a physiological cycle, the characteristics of secretions also change regularly. Normally, the discharge is drier, thicker, and less in quantity. During ovulation, the secretions will become clearer and more transparent, like egg white, with a high degree of metallic brushing. This is because during ovulation, higher concentrations of estrogen are produced, which act on the columnar squamous epithelial cells at the cervical opening, causing them to secrete a large amount of secretions.

Can I get pregnant if I have sex without breaking my hymen?

Generally speaking, it is not easy to get pregnant under such circumstances. The broken hymen is basically intact, and pregnancy is just an accident. In order to get pregnant, there must be fusion of sperm and egg. The man ejaculates inside and outside the vagina during excitement, but some of the male sperm has already entered the vagina, and the woman happens to be in the ovulation period. Young and strong, coupled with an excited and arousing environment, the sperm density of men must be at a higher level (usually 2-6ml). Therefore, even if no ejaculation occurs in the vagina, some of the sperm may be injected into the vagina due to the high sperm density. Although women have a broken hymen covering the vulva, there are still many gaps in the normal hymen (menstrual blood is discharged from these pores in the membrane) so if there is a drop of sperm flowing into the vulva, it will go through the ovulation tube into the uterus and fertilize the egg. Originally, during sexual intercourse, sperm is stored in an area deep in the vagina called the posterior vaginal cavity (called the "sperm pool" in ancient books). This point is closest to the cervix, which makes it easy for sperm to pass through the cervix, through the uterus and reach the fertilization site in the outer 1/3 of the fallopian tubes.

If sperm cannot enter the cervix, it can only survive in the acidic and alkaline environment of the vagina for a short period of time of six to eight hours. It is not difficult to imagine that the boy's sperm must be very healthy and energetic. But this is just a criterion. A key reason why male sperm is not killed by the acidic and alkaline environment in the female vagina is that women help a lot. It turns out that during the ovulation period, the secretion of the cervix increases to 0.5ml per day (0.1ml per day in other periods), and when the sexual desire is highly stimulated, the secretion volume can continue to increase. The fluid secreted from the cervix is ​​weakly alkaline, which can neutralize the acidic and alkaline environment in the vagina, thereby protecting the sperm retained in the vagina and prolonging its life.
