Hi Mum2 How regular are your cycles? I was in the same boat as you - 4 days late, and a BFN. A few hours after I tested AF showed up But I've only been off the pill 2 months, so I'm realising I most likely don't O on the same day each time. So if you're only one day late you may have just O'd later than you thought and your BFP may be just around the corner Sending lots of babydust your way!
