Hi,

Thanks for the query.

First, the drugs you are taking (Inderal, Topomax, wellbutrin, Xanax and Ambien) do not influence the results of pregnancy test. Therefore they do not cause false negative pregnancy test.

As the tests are negative it is unlikely that you are pregnant. You can however consider other tests such as
- Blood beta-hCG (Human chorionic Gonadotropin) level
- Ultrasonogram.

The aforementioned will rule out pregnancy beyond all doubts.

Hope this answers your query. Let me know if you have other concerns.

Regards
