5weeks 4days bleeding after ultrasound

Hi, so I thought I was 6 weeks but I went and had an ultrasound done yesterday and they said I’m 5 weeks 3 days, which isn’t surprising either way, sometimes my cycle lasts a few days longer. Anyways- Saturday I started having light pink/ brown spotting. Very very little. It was on the toilet paper a few times that I went to the bathroom. Well yesterday after the teansvaginal ultrasound I started having some red- period like spotting. Not enough to soak though anything. Just enough when I wipe. Today it has been dark red/brown. I’ve had light cramps since I found out I was pregnant. Not consistent, just sometimes there. Has anyone else experienced any of this? Only symptom I’ve had is spotting, cramping, sore breast. I know I’m still early and it’s basically a waiting game. Dr doesn’t want me in for another two weeks. Hoping to hear some positive stories similar to mine. Dr said it’s common but I’m needing some reassurance
