Ok. I know this is silly. I did a Sainsbury’s test 10dpo. It went quickly negative (I didn’t wait 5 mins). Tossed it in bin and went back to sleep for an hour. Of course, had another look and there was a faint blue line of the correct thickness. Extremely faint though. I then did a boots 25miul test this morning and v negative. Now I can’t get it out of my mind. Shall I disregard the Sainsbury’s test?
Thanks for your help!
