Has anyone ever used this kind of ovulation and pregnancy tests? My husband and I are trying for number 2 and I'm 5 days late but I'm getting negative results on the pregnancy test. I bought this kit from Amazon so I'm just wondering if anyone's ever had any false negatives with this kind of test. It's a pink dye test and I thought pink guy was supposed to be more reliable than blue dye. But there's not even an EVAP line on these. With my first baby when we were trying I got several evap lines that I thought were positives before we actually got pregnant.
