Day 28 is tomorrow but even though I was 99% sure I couldn't be pregnant still couldn't stop myself from testing. Yesterday was negative with a Clear Blue, this morning I had a faint positive line from a Clear Response, so I doubled checked with a Clear Blue an hour later and it was negative. I've just done another and that's negative...don't know what to think. I left the 'positive' test out for 20mins before double checking it because at first I only saw what I thought was negative result. Could there be hope?! I'm probably clutching at straws.......
