I took a pregnancy test. Sainsbury’s own brand pink dye tests. Test showed nothing and I went off to finish some housework. I came back around an hour later to throw the test away, and there was a faint line. I thought evap line but it was slightly pink. I tested again and within 10 minutes it showed another very faint line but again it was pink. I did a clear blue 6 days early test and a faint line was visible immediately. When I tested again (Tesco own brand and a cheap pink dye they were both negative. Could it just be that the last two that I took weren’t sensitive enough? I’m due for my period in 5 days.
