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.
The Test Is Done too Early. Pregnancy tests look for the pregnancy hormone HCG. This takes time to build up in the system, if the test is done before there is enough of this hormone, it will be a false negative. This usually happens when women test before they even miss their period.
