Af is now 10 days late but keep getting bfn. I have been going off date of last cycle over 6 weeks ago and thinking surely it would show on test by now. As we only BD'd once this month I would know the exact date of conception. Using this date (2 weeks ago, obviously ov'd late) would mean I was 4 weeks pregnant and that is probably why I have been getting bfn up to now as it has been too early. I'm allowing myself to get excited and hope I get my bfp in the next few days. Just hope I'm not disappointed :-/ x
