After pregnancy, menstruation will no longer occur, but some people may experience menstrual discomfort and may also have periods after pregnancy. So it may be a sign of miscarriage if it's not suitable for menstruation. How to confirm pregnancy? Usually, it's tested with test strips at home. So, what's the reason for weak positive test results on the day before menstruation?
What's wrong with weak positive test results on the day before menstruation
1. If it is weakly positive, there is a high possibility of pregnancy, and it is necessary to check blood progesterone and HCG for diagnosis. It is recommended to go to a regular hospital to check blood progesterone and HCG to determine if it is positive.
2. HIV testing is divided into initial screening tests and diagnostic tests. The initial screening test has a higher sensitivity, and a weak positive is the possibility of appearing during the test, which cannot be fully determined and requires further testing to confirm. Without a clear examination, there are many items to be checked in the hospital, and positive, negative, and false positive results may occur.
How to correctly detect weak positives
1. The situation where the early pregnancy test strip is one deep and one shallow is called weak positive in clinical practice. At this time, the possibility of pregnancy should be highly considered. Testing should be done early: generally, testing should be done one week after the cessation of menstruation, and the results are more accurate. At this time, the secretion of HCG is significantly increased. If tested in advance, there may be a weak positive reaction due to insufficient concentration in urine.
2. Dilution of urine, if drinking too much water to dilute urine, may lead to weak positive results; Using expired or damp test strips may result in weak positive results; The depth and depth of early pregnancy test strips should also consider self-test results caused by non pregnancy factors, such as blood in urine, endometrial hyperplasia, ovarian tumors, previous pregnancies, expired or incomplete abortions, etc.
When pregnant, use test strips, which are both simple and convenient, and have a high accuracy rate. The accuracy rate is over 90%, but there are also errors caused by improper operation. If you want the most accurate answer, you can go to the hospital for a urine test or do an ultrasound to get the most accurate answer. Couples who do not want a baby should take good contraceptive measures.
