Counting down the days

Next Thursday we get to hear the heartbeat. I’m trying to stay positive!! Just had some aches, pains, little spotting, cramping but doctor was not worried. Had an ultra sound at 6 weeks and all was good besides blood behind placenta, which puts me at a higher risk for miscarriage but I cant help stressing that maybe I’m not pregnant anymore? Anyone else feel this way?? Just hoping for the best!!!
