I am due on end of the week, but last few days felt nausea & I was put on metformin nearly 2wks ago. I done a cheap test other day of which i thought was a faint line, so done a digitial clear blue that came back 'not pregnant'. So i decided to do my last cheap one this morning. Top pic was from couple of days ago & bottom is from this morning

I have since been & bought a first response & done this afternoon!
