Re: How soon can one take a home pregnancy test?
Tests can give a false positive, it all depends on how sensitive they are, how much growth hormone you have in your urine and how accurately you use the test. If you are likely to be pregnant don't rely on the first test.
If you can't wait till Tuesday go ahead and do another test, but beware that it, too, could give a false negative. You should know for sure after you've visited your gynae.
