Clearblue is the #1 selling brand of home pregnancy and fertility tests, and is also the #1 OB-GYN recommended brand of pregnancy and fertility tests. The line of Clearblue products consists of Fertility Monitors, Ovulation Tests and Pregnancy Tests. The Clearblue brand is owned by SPD Swiss Precision Diagnostics GmbH, and was started in the United Kingdom in 1985. The first home pregnancy test was a three step process, but over the years, Clearblue has streamlined the process, and it's now a one step kit. Clearblue products can get expensive, since most couples end up buying more than one kit. Keep costs down by using coupons on Clearblue products. Find coupons here at GCN and save money!
