Thanks for the help Sharon and Leah. There is still no sign of AF so I think I may do a test tomorrow. I still keep getting slight AF cramps but nothing has happened since that very tiny bit Tuesday night. I am going to the doctors next Tuesday so I can work out what is happening.

Leah, do different tests give different results? The one I tried was Fortel ultra meant to detect HGL or whatever at very low levels. According to the test it should work 5 - 7 days before AF is due. I am certain I O'd 19 days ago now? Does that mean I am definately not pregnant, or if I am something is wrong because I don't have high levels??

Thanks again
