Is it accurate to test blood for delayed menstruation for two days?

If your period is delayed for two days, it is inaccurate to do a blood test at this time, because there is still no way to detect whether you are pregnant or not. Only when you conceive after intercourse, around 16 days, can you detect it through a blood test. Generally, a few days of delayed menstruation is a normal phenomenon. Of course, for women who are preparing for pregnancy, they are eager to get checked when their menstruation is delayed, and this feeling is understandable.

How many days is it normal to delay menstruation?

There are certain medical regulations on how many days of delayed menstruation is considered normal, usually about a week.

A normal menstrual cycle is about 28 days, with ovulation occurring two weeks after the start of menstruation and two weeks before the start of the next menstruation.

Menstruation usually lasts 3-7 days, and the amount of menstrual bleeding is about 30-50 ml.

Various factors such as emotions, environment, nutrition, etc. can cause early or delayed menstruation, and it may also change from "menstruation" to "seasonal menstruation" or even last longer than half a year or even more than a year. It is normal if there is no lesion.

Many people believe that exceeding the normal cycle range, which is 25-30 days, is an abnormal physiological phenomenon. In fact, it is not as simple as it seems on the surface.

The normal menstrual cycle is 25-30 days. It is normal if it is earlier or later than a week. However, some women's menstrual cycle may be delayed to two months or even longer, such as one quarter, which is medically called "quarters".

Generally speaking, sperm can reach the woman's fallopian tube within 1-2 days after intercourse, and combine with the egg released by the woman in the fallopian tube to form a fertilized egg. Pushed by the cilia in the fallopian tube, the fertilized egg will reach the uterus after about 6-7 days. If conditions are right, it will implant in the endometrium. Implantation of the fertilized egg is a sign that a woman is pregnant. So it takes at least 6 or 7 days from fertilization to pregnancy.
