Confused

So my af is supposed to start in 2 days, but I never get cramping until I actually have it. The last 3 weeks I've had sore nipples like no other, weird dreams, and my boobs are killing me. I had a misscarriage in June, so the hubby and I never stopped trying. Only had sex on my 2 most fertile days glow told me to test yesterday and it was negative. So should I just wait to see if my af comes or should I wait to see if I have a little miracle Baby and test if I miss it?!? I just want to be pregnant so bad I think it's stressing me out lol
