I bought these ovulation tests after almost a year of unsuccessful attempts to try to put all the chances on our side, and the first month of use, to my amazement, I got pregnant ... Easy to use, with a quick and clear answer. Only downside, the manual is in English, but it can be downloaded from the clearblue site. And as a gift, 2 very early pregnancy test (10 IU), which allow to know very quickly if you are pregnant ... For me, great shopping, I advise all women who have difficulty getting pregnant.
