A negative test paper on 36 days after menopause usually rules out pregnancy, but it is important to consider false negatives as well. A woman’s normal menstrual cycle is usually 28 days, a week early or late is normal. 36 days after menopause if the early pregnancy test paper is negative, usually is not pregnant, if the usual menstrual cycle is longer, can also be a week again test, if the test paper is still negative, usually can rule out pregnancy. However, we can not rule out the false negative results caused by the quality of the test paper, the use of the wrong method, etc. It is recommended that if you suspect pregnancy, you can go to the hospital to check the blood HCG and ultrasound, so as to achieve the purpose of confirming the diagnosis, if the blood HCG is also negative, then basically can completely exclude the possibility of pregnancy.
