What to do?

Beth
October of last year, I had a miscarriage. My husband and I having been trying for 2 years. It's October again and here I am still not pregnant and I'm down about that well now AF is 3 days late. I don't have any symptoms other than fatigue and headache. I just don't know if I can or should test. On the one hand I'm tired of seeing negatives but I guess I'm scared to see a positive as well because I went down this road last year it's like deja vu. What should I do?
