Hello, I have gone through your query and understood the concern. It is most unusual for a home pregnancy test to read negative throughout the pregnancy. Either the procedure must be faulty or the test kit not properly validated. In the current scenario, Your chances of pregnancy are less likely and you seem to be experiencing transient hormone imbalance. You can exclude/confirm pregnancy through the assessment of the serum beta-hCG titres. If negative, please watch the bleeding and get help if it is heavy or prolonged. Take care.
