Does anyone know anything about these tests that you can buy from amazon? The dot (A) should be as dark or the same colour as the control spot (B). I understand that this only measures the concentration and not the quality etc. This doesn't look great right? Feel awful for him as I always thought the problem was with me (could still be, I had blood tests this week and have an ultrasound tomorrow to check my uterus). Has anyone's husband tried these and had similar results? TIA
