Positive test

Amy

So I tested this morning after having slight bleeding yesterday which I thought was my period but then it stopped. I took 2 easy@home HCG tests within an hour of each other which both showed positive. I took a clear blue how many weeks test and it came up ‘not pregnant’ could this be due to the fact I tested on my 3rd wee of the day and not my first? Or the fact my HCG levels may still be to low?
