I havent had a period since the end of march, and have took about 1 million tests, they all either come up with a thin blue line slightly to the left hand side before the ten minutes or after the ten minutes but they are all brilliant blue lines. The tests i have taken are, clear blue, boots own and lloyds pharmacies own. I have had some cheap ones off ebay which were negative and ive done doctors tests which are negative and also the clear blue digital came up "not pregnant" So i am very confused as i have had alot of these thin blue lines! Has anyone else had this problem and what was the outcome? Comments appreciated xxx
