Frustrated - could be your period - I get mine anywhere from 11 days after O' to 16 - so it could be. Apparently you can also get bleeding from when the egg implants in to the wall of your uterous - so there is my answers - I read way too much!

I am now up to day 31 - my specialist has told me to start testing as of yesterday - did yesterday and today and both negative. But AF have still not arrived and I don't feel like they are around the corner. So will just wait now!
