My PCP told me that a drugstore test is as accurate as a test done at a clinic, and there are two tests in a package so you can be really sure. Determining if you are pregnant does not require a visit to a clinic. I do not understand how it can be taboo to buy a test, unless in your drugstores you have to ASK a shop assistant for a test. Even if that is the case, it would be better to overcome the taboo, get a test, and get peace of mind from having a negative result.
