I love this pregnancy test. The first time I got pregnant I tried some others and they always confused the hell out of me (phantom plus signs, mixed with negative results from the other tests in the same box, being able to see part of the word "Not" before the word "Pregnant" etc.) And I promise I tool them all acroding to the instructions on the box. I took seven all together before I found this one. This is the only one that gave me a clear positive result! I also used it to discover I was pregnant again recently and I got another clear positive result. Very easy to use, and very clear results. I would definately recomend this to anyone.
