Yes, if you take it too early. You should wait until a week after missed period, then the test should be accurate. Take 2 tests just to be absolutely sure and do it in the morning as soon as you wake up.
A urine pregnancy test usually becomes positive three to four days after implantation or around the time you miss a period. A negative test means you are not pregnant enough to test positive or you are not pregnant.
