Women have symptoms of pregnancy, but just can not detect pregnancy, this time to consider the following possibilities: First, women are indeed pregnant, just because the menopause time is relatively short, the HCG hormone in the urine rise is not obvious, so the use of pregnancy test paper or pregnancy test stick can not detect pregnancy, generally can only be considered to go to the hospital to check the blood HCG to determine. Secondly, women are not pregnant at all, just due to the stress of preparing for pregnancy, affecting ovarian ovulation and endocrine function, and indirectly lead to false pregnancy symptoms. Third, because women have gastrointestinal diseases, so there will also be nausea, dry heaving and other similar pregnancy reaction, but in fact is not really caused by pregnancy. So for women who can’t detect pregnancy with test strips, they can directly go to the hospital to check the blood HCG, which can 100% determine the pregnancy situation.
