How long can I take a pregnancy test if my period has not come?

In fact, there are many reasons why women do not have their periods. It may be that their bodies are not well maintained, etc. So, how long after the menstruation can you test for pregnancy? This is actually hard to say, because after all, there are too many factors that affect the absence of menstruation, and it is not easy to distinguish. So let's discuss it with everyone.

How long before menstruation can be tested for pregnancy

It is the most common sign of pregnancy that people notice. As long as a woman of childbearing age has normal menstruation and has sexual intercourse for more than two weeks beyond the normal menstrual period, she may be pregnant. It is the earliest signal of pregnancy. The longer the duration, the greater the possibility of pregnancy. However, women's reproductive function is very sensitive. If the menstrual period does not come, it does not mean that you are pregnant. There are many reasons for the missed menstrual period, which may be due to poor uterine and ovarian function, abnormal male hormones, busy work, exam anxiety... etc. If the mind is under great work pressure, or there are certain changes in the surrounding environment, it will cause delayed menstruation. Women who usually have irregular menstruation do not need to be too worried if their menstruation is late once, but it is difficult to use menarche as a criterion for pregnancy. Therefore, it is best to get a doctor's diagnosis, which is the safest.

For women who have a normal sexual life, once their menstrual period is late, they should first consider whether they are pregnant. However, in addition to the absence of menstruation, it is also important to observe changes in their own physiology. Especially when a woman is already pregnant without knowing it, she may mistake bleeding for the beginning of menstruation. In the early stages of pregnancy, there will be bleeding similar to the menstrual period, but it is not menstrual-like bleeding. Some women will also have bleeding in the lower body due to embryo implantation. Although menstrual bleeding is light in color and in small amounts, it is sometimes a precursor to miscarriage. It is best to see a doctor as soon as possible for diagnosis.

Then you can test it around 40 days after the due date of pregnancy and buy a pack of early pregnancy test strips. Generally, morning urine is more accurate, that is, the first urine after getting up in the morning. Urine at other times can also be tested, but sometimes it is not very accurate. It is best to use morning urine for self-examination at home. It may not be morning urine when you go to the hospital for examination, but it can still be diagnosed, right? Pregnancy can be detected 40-50 days later, when the body's human chorionic gonadotropin is the highest, and the component of morning urine is the largest in a day, so morning urine is relatively better. If your period is delayed every month, you can just test it in a few days. ,

Ovulation

The reasonable pregnancy time during ovulation is 7 days. Since the ovulation period is not necessarily a fixed ten days, how long is the effective pregnancy time during the ovulation period? Generally speaking, the survival time of a normal woman's egg cell is about 2 days, at most 3 days, and at least less than 12 hours. A man's sperm can usually survive in a woman's body for 3 to 5 days, usually 4 days.

In other words, the effective pregnancy time during the ovulation period is generally 5 days before the girl's ovulation, because the male sperm can survive in the woman's body for up to 5 days, and 2 days after the girl's ovulation, because after the egg is released, it can only survive in the woman's body for 2 days. In other words, the effective pregnancy time is generally about 7 days.

Most people think that as long as couples have sex during the ovulation period, they can get pregnant. In fact, this view is not correct. Because pregnancy is a complicated process and is affected by many factors, whether pregnancy can be successfully achieved during ovulation varies from person to person. Having sex after ovulation only increases the chance of pregnancy, but it does not necessarily mean that you will get pregnant.

So, what are the reasons why you cannot get pregnant after having sex after ovulation?

1. It may be caused by cervical disease factors. It is a key cause of infertility, accounting for about 10% to 20% of infertility. Due to chronic cervicitis or low estrogen levels, cervical mucus may become thick or contain a large number of white blood cells, which is not conducive to the activity and passage of sperm and may affect pregnancy. In addition, cervical cysts or cervical fibroids can block the cervical canal and affect male sperm. The narrow cervical opening may also be the cause of infertility.

2. It may be caused by some factors of the female ovary. For example, congenital absence of uterus and ovaries or infantile uterus and ovaries, ovarian aging, polycystic ovaries, and some uterine and ovarian tumors such as granulosa-ovariocytoma and uterine ovarian blastoma can affect the metabolism of growth hormone in the uterus and ovaries and the ovulation period.

3. It may be caused by women’s systemic diseases, or the lack of some important nutrients in the diet can affect ovarian infertility.
