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 take the test and it is positive then you are most definitely pregnant. That is because the pregnancy tests only detect the pregnancy hormone in your body. There is nothing in the birth control pills that could be mistaken for the pregnancy hormone or cause a false positive.
