I had a positive pregnancy test about 3 weeks ago, I did a clear blue one which said I was 3+ weeks. I had some bleeding and mild cramps - I would have just thought I was on my period but I booked a private scan and she said there was nothing there. I was told that it would take 2 weeks to get a negative result again, I’ve took another test and it still says positive? Can the clear blue dates be wrong that they say you are further along than you are?
