Over the years I have had to take several pregnancy tests. I have had 2 children, a miscarriage, and my periods can be irregular, so there were times I thought I was possibly pregnant when I wasn't. Needless to say, I have tried several different pregnancy test because of this. I must say that First Response is by far my favorite one that I have used. It is SO EASY to use and it is very accurate (I was only 3 weeks pregnant with my son when I got the positive result)! I would recommend First Response to anyone who wants to find out quickly and easily if they are pregnant! It is very easy to use, very accurate and very easy to read your results!
