ve heard that diuretic medications can cause a false negative pregnancy
test. I can see how this would interfere with a
urine test if the diuretic is diluting the urine, but can it also cause lower levels of hCG to show up in the blood?
Also, another awful thought is if levels of hCG are too low to detect in the blood 25 days after conception could that mean miscarriage or something wrong with a pregnancy?
