Hello there ladies, AF STILL hasn't come, and yet I'm still getting

!
Have finally got an app. with doctors for this friday, although I'm worried she's going to just have me POAS and then send me away...
Have had a rather nasty pain in my right breast for a while now, at least a week, only when pressed but there's none in the left. Also getting rather bloated... I just don't know what's going on with my body ):
I've never had trouble with AF before, always been regular, and now, nothing, and yet the tests are telling me there's no reason for this lack of monthly bleeds!
Edit - Just calculated how far along i'd be if I was pregnant by my last missed period, turns out i'd be 9 weeks along if the tests are wrong!
