Well what kind of test did your doctor do on you pee or blood test because the blood test is more accurate than the pee and yes you should do the test again just to make sure

If you took a blood test at the Dr. Then your not but if you took a pee test. You should have your dr do a blood test. There is a hormone in your body that tells if you are pg or not. Some wemon though have it even if they ar not pg and home pg test some positive when you are not pg.

Well you should take a few more tests to find out and then call the doc if they are still postive. There was another girl in here with the same exact problem and she did what I said and she went to the doc and sure enough...She was pregnant! Good luck. Let us know what happens!
