You took a pregnancy test and it came out positive you are also almost 2 months late on your period is this a phantom pregnancy?
If your pregnancy test is positive then most likely you are. You would be more likely to get a false negative rather than a false positive. If you are unsure, you can request a beta HCG test from your doctor. This will measure the HCG hormone in your blood system which is an indicator of pregnancy. The pregnancy test is positive and you haven't had a period in two months. I see nothing to indicate that this is a 'phantom' pregnancy other than maybe wishful thinking. I've been told that the home test kits may give a false negative, but that they never indicate a false positive.
