In this study, a group of 346 women were trying to get pregnant in a natural way by monitoring the basic temperature chart of the body, observing cervical mucus to determine the most fertile relationship date.

The results showed that after a month of trying, 38% of women became pregnant, 68% became pregnant after trimester, 81% after 6 months, and 92% became pregnant after 12 months.

Of the 346 women, only 36 could not get pregnant, accounting for about 10%.

Couples who cannot become pregnant after a year (the wife is over 35 years old) and after 6 months (the wife is under 35 years old) are considered infertile and need to see a specialist.

Statistics show that about 10% of twins do not get pregnant after 12 months but after 36 months of trying, half of them are already pregnant.

About 4% of couples are unable to get pregnant despite the effort over the course of 4 years. They need medical help to become pregnant.

To calculate exactly how long it takes to become pregnant is not easy. The process of fertilization between the egg and sperm is not yet called pregnancy.

Couples who have undergone IVF and embryo transfer without “sticking to the gourd” can clearly understand this problem. To get pregnant, the embryo needs to be implanted in the endometrium.

In addition, sperm can remain in the female reproductive organs for up to 5 days.

Suppose if you have sex at 22pm on monday but ovulation takes place around 7am on Thursday, fertilization can still occur even though it is less likely.

If considering the period during which sperm persists until fertilization and nesting, successful pregnancy takes a period of 7 to 10 days.

Several factors can affect the progress of pregnancy.

First it is such luck as having to occur the process of ovulation, fertilization, nesting, the embryo develops healthy and stable.

Up to 70% of cases of early miscarriage are caused by genetic malformations in the embryo.

The frequency and timing of intercourse also determines whether you are pregnant or not.

Age and weight also affect the duration of pregnancy.

The older women and men are, the longer the period of conception. This is partly due to the deterioration of egg and sperm quality along with an increase in faulty DNA.

Obesity or severe underweight can also prolong pregnancy.

Besides, factors related to fertility in both sexes are a factor to consider.

The most obvious sign is not getting pregnant after 6 months to a year despite constant attempts.
