I haven't done a test because I kinda feel silly and I think I know that I am not pregnant.

I just thought that I would mention the AF and getting a +ve only 13 days after. I definately had AF, if fact I spot bled for 5 days before AF started and then got a full AF. When I m/s my HCG levels were 1000 which is about 5 weeks.

Clare when did you bleed through your pregnancy?
