Oh Amy i know it must be so frustrating! are you starting this month or just keen for AF to arrive because she is late? I tink the nurses just like to make sure its all over, i had to keep going back in to after my miscariage until my level was back to 0, its horrible because i think we always hold hope that maybe our embie is still there even know deep down we know its a waste of time. Like i said my AF after my miscariage was 10 days late but then my last 2 have been spot on 28 days like normal so it will hopefully just be this one out of whack for you i hope she does comes soon for you xxx
