So clear is always a second Struch there! LH is also always in the body! Only it rises up enormously if you have your ovulation. And this increase can also be seen clearly on the tests. Because then the line is slightly pink or a little pink but just as intense or even more intense than the control line. So now to my review: I did not really how hard it is to become pregnant ... 2 years ago my husband and I decided to try to have a child .... sooner said than done ... ... pill sold immediately in the cycle after withdrawal bleeding I was pregnant! Now after a year (exactly last year March), we decided not to get one because I have said if I then immediately afterwards (ie after the 2nd qualifying period) soforr can go back to work. Well until last month it did not work so I decided to buy me this Ovus ... I measured from the 9th day of the cycle and then also clearly recognized when the it was. Well what am I supposed to say ..it was 10.3 and 3 days ago I have a cheap test done that showed soft pink pos ... and today I made a CB Digi and there stood Pregnant 2-3: D So 1 ÜZ with these Ovus and it worked :) I can only recommend :)
