I was due on on Tuesday, tested tue night and bfn, tested wed morning fmu and thought I had an extremely faint line but couldn't convince myself (it was that faint). I tested this morning with a first response early detection test and got a very faint (but definitely there) line. The thing is, with my successful pregnancies I have always had a strong positive when af was due and the only time I had a faint one when I was late, I went on to miscarry. I suppose I am just after other peoples experiences, I know I need to wait and see but I really don't want to get my hopes up
