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.
One of the most common reasons for a false negative result is testing too early. In order for a pregnancy test to show accurate results, you have to give your body time to produce the levels of hcg (pregnancy hormone) that the pregnancy test needs in order to trigger a positive result.
