Hello, I would be happy to assist you.
It certainly is possible this was a false positive test. This occurs more often when using off brand tests, or in all tests if read after too much time has passed. With PCOS, it is not impossible to become pregnant, but is difficult. I recommend you visit a gynecologist to obtain a prescription for Clomid, a pill to help you ovulate, in order to conceive. It certainly helps many women with PCOS.
You can certainly repeat the test with another name brand test to break the tie (like Clear Blue). Alternatively, you can ask your gynecologist to perform a blood pregnancy test as well.
I wish you the best. If you have additional questions, please ask. If none, please click "Accept." Thank you.
