Hi i did a pregnancy test yesterday 2 days before my period using a test which has a 25ml sensitivity and it came up with a faint line which is the one on the left on the picture below then I did another one today which is one day before my period and it’s darker one on the right, however I did a test while at home first urine of the day using a pregnancy test which has 10ml sensitivity and it came out negative I used the Superdrug early response one, I don’t get why when I use the tests at work they come out with a faint line but that was negative but more sensitive?. Can anyone help?
