Hi, I'm on day 43 of my cycle so 10 days late. Various things going on so didn't really realise until yesterday and picked up a 2 pack of tests after work. Tested straight away and had a positive test, tested now this morning and it's negative. I'll try and buy a different brand after work today but anyone else had this? I thought false positives were rare but can't see anything at all on this mornings.
