I think unless you've had some medication in it with hCG lately (usually fertility drugs) that you are most likely pregnant. I don't believe there are any hormones that fluctuate with menaupose that would cause the false positive, hCG only rises with pregnancy and that's the only thing that the home tests look for. Hypothyroid medication wont affect the pregnancy tests.
Blood or protein in the urine may cause false-positive pregnancy results. Urine hCG tests may give a false-negative result if the urine is too diluted or if testing is done too soon in the pregnancy. Certain drugs such as diuretics and promethazine (an antihistamine) may cause false-negative urine results.
