I haven't experienced that, I've always had positives before AF was due. If I was getting negatives and I was late I'd wait until I was two weeks late before seeing a doctor. I've seen lots of ladies who've been a week to 10 days late who were not pregnant on this forum. Sometimes your cycle just goes out of whack and your cycle goes longer.
If however you have been charting and you know you O'd say 3 weeks ago I'd go get a BT straight away.
