my first test showed a faint but obvious positive line . 2 days after that i took two pregnancy tests the one showed a negative and the other showed an even fainter positive than my first test
Are you using first morning urine to take these tests? If you are testing in the afternoon or evening your urine might be too diluted to make a positive result. Also if your period is not due yet it might be too early to get a good positive result as your hormones have not built up enough.
