Pregnancy tests are usually dark and light, and if the control line is clear and the test line is very light, it means that you may be pregnant, but not necessarily that you are pregnant. Of course, the pregnancy test a shallow depth may also be due to external reasons, if the pregnancy just or ectopic pregnancy such as ectopic pregnancy, the body HCG level is generally low, the detection area of the ribbon only vaguely appeared will also lead to a shallow depth of the pregnancy test; in the very case, such as grapes, choriocarcinoma, the body HCG level will be too high, the urine test and does not show a positive; after three months of gestation, the level of HCG declined, the urine test will sometimes show a negative. The urine test will sometimes be negative, or weakly positive. In addition, a fertilized egg does not secrete HCG until 7 days after it develops, so you should not test the day after intercourse. Since a woman's day of ovulation is usually in the middle of two menstrual cycles, for example, a 28-day menstrual cycle, the day of ovulation may be around the 14th day, and since it takes about 7 days for implantation to occur and some time for the secretion of HCG to increase, it is generally recommended to take a pregnancy test after the next menstrual holiday for a higher rate of accuracy.
Possible reasons for a pregnancy test 1, early pregnancy, low HCG. When you are just pregnant, HCG levels are generally low, and the color band in the test area is only vaguely visible, which can also cause the pregnancy test to be darker and lighter. At this time, it is recommended that the next day and then use the morning urine test, such as the contrast line color becomes darker, then congratulations, the honor of the mother-to-be. 2, urine concentration is too low. In the mom network, the newly pregnant pregnant mom said, obviously the morning test is still positive, but in the afternoon became weak positive, was confused. In this case, it is likely to be because the urine concentration is too low. The recommendation for the proper use of pregnancy test paper is to try to use the first urine in the morning for the test, as this is the time when hormone levels are most easily detected. If there is no urine in the morning or if you have drunk too much water the previous night, then at least make sure that the urine has been in the bladder for at least four hours before using the test. Otherwise, it is easy to cause the pregnancy test paper a deep and shallow situation occurs.3, pregnancy test stick is too sensitive. Ovulation, women's HCG and LH will reach a peak, after ovulation will return to normal levels, however, close to the next menstrual period, these two values will rise a little bit, if the pregnancy test stick used is too sensitive, it is easy to show a shallow detection line. On mom's website, this kind of "what Hu" situation is quite a lot, many users have responded to the use of Xiuer pregnancy test stick will be more sensitive, accidentally on the empty joy, the proposal is to use David ovulation test paper. Pregnancy test is not a universal thing, his results are not necessarily very accurate, but I hope that everyone in doubt whether they are pregnant when it is best to go to the hospital to check the body, especially some female friends will have occasional stomach pain symptoms, this time do not delay their own!
Pregnancy test a deep and light is pregnant generally speaking, the regular brand of pregnancy test stick accuracy rate of about 85% to 95% or so. So, the pregnancy test is not 100% accurate, not to mention the pregnancy test a deep and light does not mean really pregnant, even if the detection of 2 bars, sometimes may not be really pregnant. If you want to confirm whether you are really pregnant or not, you still have to go to the hospital for a more accurate examination. Specifically as follows: 1, only a control line appears on the pregnancy test stick: that is not pregnant. 2, two lines appear on the pregnancy test stick, that is, the control line and the test line are colorful, and the test line is obvious and clear: that is pregnant. 3, no control line appears on the pregnancy test stick in 5 minutes: that is, the test is invalid or failed. 4, the pregnancy test stick is deep and light: in general, if there is a control line is obvious and clear and the test line is light, then the test line is light. indicates that you may be pregnant, not necessarily that you are really pregnant. In this case, you need to use a new pregnancy test stick to collect morning urine every two days to re-test. To summarize, one dark and one light color on the pregnancy test indicates that you may be pregnant, but it does not exclude the possibility of ectopic pregnancy, or the embryo is still unstable, so the control line on the pregnancy test is not very strong. In this case, it is recommended to test again every few days, and for insurance purposes, go to the hospital for further examination to confirm, so as not to cause accidents.
