Should I even hope?

Last month on July 2nd I began my miscarriage, it's was an early pregnancy about 5 weeks and when my mc began I only bled for 4 days. My husband and I decided not to wait and continued trying. Now here I am 3 days passed my expected AF and getting bfn. I know that after a mc your cycle may be off but I know I ovulated on the 20th or 21st. Last time I didn't get a positive test until I was about 5 weeks, right now I'm sitting at 4 weeks 2 days if I am pregnant. I'm holding on to hope that maybe in 5 days I'll get a positive like last time but then I'm still thinking that it most likely won't happen and it's just my body being out of wack. This really sucks and I don't know how to feel. Anyone else been there?
