advice please..

I am hoping for some advice. We had a miscarriage at 5 weeks? We waited a week and then continued to try. I have been told just to treat the miscarriage bleeding as my AF which was always v regular at 28/29 days. I would now be 8 days late but too scared to take a test for fear of disappointment. Anyone else had this experience? Am I just getting back into cycle or could I be pregnant??
