Ruth- ah...the POAS do drive you mad...i caved every time...and when I was pregnant last time, and had the faint faint lines at about 11dpo...I then wondered what that meant, and would it be a chemical pregnancy and come to nothing etc...but at the same time, I think i would be a little hopeful if I was you....there is obviously some hcg in your body...so something has happened in there!..hopefully you will see the lines get darker (I know you will keep testing ..i always do..I still am even now, just to confirm the lines are darker!)

jen- same advice goes to you...I POAS about 4 days before my blood test during my FET and got faint positives....but then you might still worry ..and also,it could be early, and you could get one line, and then you will also worry...I guess you just need to be prepared....I know, given my past experience and behaviour, I would probably cave and test
