Is it accurate to test for pregnancy before menstruation?

Many men and women do not take any contraceptive measures during sexual intercourse, which is very likely to lead to pregnancy. However, in the first three months of pregnancy, the belly of a woman will not grow larger, so there is no difference between pregnancy and non-pregnancy in appearance. However, some people do not have menstruation and are very worried about pregnancy, so they will use pregnancy test products to test whether they are pregnant. So is it accurate to test for pregnancy before the menstrual period?

Can I detect pregnancy before my period?

If a female friend is pregnant unexpectedly, the test results can usually be obtained on the sixth or seventh day of pregnancy, so female friends can postpone the test for seven days after the sixth or seventh day after having sex, or if the period is due but has not come, so that the test results will be more accurate. It doesn’t take long to detect pregnancy using a pregnancy test stick, but if you want the test result to be accurate, you also need to use the pregnancy test stick correctly.

There are always individual differences. Many female friends have not had their periods for a long time. How long does it take to detect pregnancy using a pregnancy test stick? According to relevant surveys, the time it takes for each pregnant mother to detect pregnancy using a pregnancy test stick varies. The earliest mother found out she was pregnant six or seven days after having sex, while some mothers found out they were pregnant using a pregnancy test stick one month after the fact. This is because the pregnancy test stick is used to determine whether the pregnancy is positive or not by testing HCG. The time when each person secretes large amounts of HCG after pregnancy is different, so the results of pregnancy tests using pregnancy test sticks are also different. When using a pregnancy test stick, it is best to use the first urine test in the morning so that the result will be more accurate. The earliest time it can be tested is six or seven days after intercourse, and the latest time it can be tested is one month after pregnancy. There are certain individual differences, so the answer to the question of how long it takes to detect a pregnancy test stick is also different.

How many days does it take to detect pregnancy?

The test can be done 7-10 days after sexual intercourse. Of course, the longer the time, the more accurate it is.

The working principle of early pregnancy test paper pregnancy self-test is to detect HCG value, that is, the value of human chorionic gonadotropin. This hormone is produced by the placenta and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is difficult to test it at the beginning and it becomes increasingly obvious after 10 to 14 days.

HCG levels can also be measured through blood tests, which are much more accurate.

It should be noted that although many types of early pregnancy test strips indicate that women can do self-tests for pregnancy one day after missing their normal menstrual period, in fact, not all pregnant women emit HCG hormones at the same rate and in the same amount. This varies from person to person. If a urine test is done too early, a negative result may be false.

1. Signs of pregnancy

Menstruation stops. Girls who have just reached their first menstruation may not have regular menstruation, but if their menstruation is regular but does not come on the day it should have come, and if they have had sexual contact with the opposite sex, sexual intercourse, or the other person ejaculated outside the body (sperm can survive outside the body for 2 to 3 hours), they should be alert.

Secondly, the breasts will become larger in a short period of time, and later there will be frequent urination and increased body temperature.

Symptoms such as nausea, vomiting, and greasy stools may not appear until three to five months into pregnancy.

2. Inspection methods

If in doubt, don't be afraid to test it yourself first. Use early pregnancy test paper and buy it at a regular pharmacy. It is a urine test, so there is no need to worry. The test paper has a relatively high accuracy rate, but it is not foolproof! So further testing in the hospital is needed. The check-up at the hospital will also include urine sample testing and B-type ultrasound examination. Don't worry, there will be no harm.

How to calculate the safe period: For women with regular menstrual cycles, ovulation occurs approximately between two menstrual periods. If sexual intercourse is avoided for 4 to 5 days before and after ovulation, contraception may be achieved.

The safe period is not necessarily safe, because sperm can survive in the cervix for a certain period of time, there is the possibility of sexual intercourse inducing ovulation, and the length of the menstrual cycle varies, so the failure rate is relatively high.
