Impossible to get a false positive - when you are pregnant, you have hormones in your body that you don't have when you are not.
The hpts state that, the only time you can get a false positive result are:
a) if you leave the test for longer than the 10 minutes stated. This is because you can get an evaporated line (usually silvery in colour rather than the colour of the test ink) when urine dries in.
b) If you have been taking hormones to try and become pregnant - for treatments like IVF.
c) If you have recently been pregnant and your hcg count has not gone down to 0.
Best of luck to you FJL - I am sure it is a BFP!!! CONGRATULATIONS!!! You certainly deserve a BFP hun! xxx
