3 days late now and no sign of af at all!!! I had my u/s yesterday which was booked before all of this but it would be too early to know or see anything really. I'd had some mid cycle spotting when I was on the mini pill. I guess I'll just ask my dr to fax in a req for a blood test and see what that says because right now nothing is making any sense because if this was a chemical I should have started bleeding by now I've never gone past 2 says late with one... bah humbug
