am I naive to feel "safe" now at 6w 2d?

My miscarriage of my last (first) pregnancy was between 4 and 5 weeks, and I don't want to jump the gun or jinx myself but I just feel like I'm safe now and can see myself bringing home a baby in September. I haven't had any bleeding or spotting at all, but light, occasional cramping which is a good sign anyway. My symptoms are strong. I'm getting super dark positives so I'm assuming my HCG is high. Am I being naive? I just can't see anything going wrong at this point, which is odd because at first I was super paranoid and never thought I'd enjoy this pregnancy.
