I had a tiny bleed (not enought to call it a bleed really) about 2and a half weeks after the start of AF. Then next AF was 3 weeks late.
In the meantime, I had pregnancy symptoms - feeling slightly sick, sore boobs etc for a week, which then tailed off a couple of weeks before AF eventually started.
I had a scan the day AF started, and was told everything looked normal for mid cycle (even though AF started that day)
I don't seem to get positive tests, which is why the Dr's arranged the scan.
Anyone know why this might have happened - the Dr's said this sometimes does, but couldn't say why, and this has never happened to me before, or anyone I've talked to.
