I took an ultra early pregnancy test this morning, which is meant to show results 6 days before your due date. I am currently 4 days before my due date. When I did the test it was negative, but when I checked back a couple of hours later there is a faint blue line. I know this could be an evaporation line but I’ve never had this before, especially not blue in colour. I only gave birth to my daughter in April so feeling very apprehensive!
