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.
If you get a false positive from a home pregnancy test, it is usually the result of faulty test strips. Most home pregnancy tests now have an indicator that shows whether or not the test is working correctly. If you leave your pregnancy test too long before checking it, this can also cause a false positive.
