Error on home pregnancy test

Lauren

So my bf and I have been trying since October and I suffer from pcos. I had a period dec 22 after going off birth control oct 22, since no period. I have tested every other week since missing my period to ensure I can track properly. Today I bought the digital test that reads pregnant or not pregnant. After taking it early in morning it came back reading error with a book. Now I’m nervous to test! Anyone else experience this and get a positive after!?
