Bleeding and cramping 5.5 pregnant

Pretty TMI but I’m 5 weeks 5 days pregnant i thought i was a lot further than that due to taking 4 pregnancy test on 5/24/19 and BFP. I’ve had mild cramping and sore boobs but recently my boobs stopped hurting and the cramps seem more. When i went for my ultrasound yesterday they determined i was only the 5.5. But yesterday and last night the cramps were more consistent, i woke up to what i thought was discharge but blood instead. I’m freaking out and called my dr who didn’t seem that worried. I go in later this afternoon for blood work but the bleeding only happens when i push or if i push harder on the tissue paper. Should i worry of miscarriage? Anybody have similar symptoms?
