Thanks everyone. My AF did come but was much lighter and stopped the next day. (And like you Kbgirl I had massive cramping) Normally I'm 5-7 days long and heavy without fail. But I went to the Doc this morning (as I'm bout to go away for 5 weeks and wanted to sort it out) and just did a normal test which was BFN. She said I'm probably not pregnant and I probably just didn't ovualte this month which caused the light, short AF - but just to wait and see what happens next month. So that's ok - I'll just assume I'm not and see what happens. But I'm sure I ovulated (had EWCM), I've never had a short AF before and everything tastes funny. I'll just wait and see I guess and take it as it comes. I am off on a 5 week holiday to the UK - never been before, v exciting! Thanks for all your advice.
