I got a pack of 50 'proMatris One Step Ovulation Tests' from Amazon. I was getting no second line then yesterday and today I have what I believe to be positive?! I have very long very irregular cycles and have had 3 af in 20 months. After reading about them there are mixed reviews, some say they are brilliant and some say they give false positive. I have never had 2 lines on any test so am just worried this is false especially as my boobs arent sore and only have a few niggles on my right side does anyone have any thoughts on them? Thanks in advance
