Q: 1. What is an expired period? For example, it’s usually a 28-day cycle, and the last time was July 3. Is it considered past due if it doesn’t come on August 1? Menstruation can be early or delayed, maybe a week after August 1st. If the menstrual cycle is not allowed, how to calculate ovulation. 2.What is the relationship between menstrual period and early pregnancy test? People who are not allowed to menstruate, how many days after the expiration date can be more accurate to check the pregnancy (early and early pregnancy test paper). Answer: 1, the menstrual period This is a folk saying, or “commonly known as”. The menstrual period should not come, not according to 28 days, according to the day I should be counted, such as the last time is July 3, if she should be July 31 to come, that August 1 did not come is the “menstrual period”, but over a day does not mean much (because of menstruation may be early or delayed), over the 7 days of pregnancy may be large, over the 10 days! Basically, you are pregnant. If you have an irregular menstrual cycle, it depends on how irregular it is. If it is always a week early or a week late, there is a pattern to be found. If there is no regularity, it is necessary to combine the early pregnancy reaction time, the size of the fetal capsule, the length of the fetal buds, the appearance of the fetal heart time, the time of fetal movement, the ultrasound value of the diameter of the expected date of delivery. 2, menstrual period and early and early pregnancy First of all, it is necessary to clarify what is early and early pregnancy. Generally 10 days after the menstrual period, can be detected by urine pregnancy test, before that ordinary means of detection is not easy to detect pregnancy, called early pregnancy. That is: the number of days of pregnancy is less than 40 days (some scholars believe that it is 35 days ago, some scholars believe that it is 37 days ago, some scholars believe that it is 39 days ago) is early pregnancy. Early pregnancy test strips usually detect pregnancy before 40 days of gestation, only a little more sensitive. For people who are not allowed to have their periods, you can test again a week after the test is negative. Clinical things are not like the people think that mechanical, have to be a few days a few positive, because ovulation varies from person to person, the same person also has fluctuations, and early pregnancy test or early pregnancy test, what do you want to achieve? The only thing is to be or not to be, to be, there is no abdominal pain and bleeding, what is your hurry? No, 45 days before pregnancy, usually the fetal sac is too small, easy to miss suction, not suitable for abortion. Besides, the visual abortion, can you “see” the embryo? It’s like typing, looking at the keyboard or typing blindly, which one is better? But some people insist on saying that “visual” is an improvement, not all wrong, first see, may be more targeted, but I do abortion by feel, probe and suction tube have a “soul”, than “visual” much more advanced. But I do abortions by feel, the probe and the suction tube have a “soul”, much more advanced than “visualization”.
