Af isn't due till feb 12th. But I had some hpt here so I caved & tested I got 3 very faint positives. One at 7dpo with ept. & 2 other faint positives at 8dpo with ept. But used a different brand & got a negative. Could it just be too early for the other brand detect ? I plan to try & test again on feb 8th. 4 days before af. But I'm really worried. I had a miscarriage in a august 2014.
