Pink spotting after transvaginal ultrasound

Is this pretty common? Kind of worried considering I thought I was miscarrying and that's why I had an ultrasound done. And immediately after I had a bunch of pink spotting, hours later still cramping and spotting more than before my ultrasound. The lady had the ultrasound in me for 10-15 minutes instead of about 5 like last week. 8 weeks today and hope I'm ok from that
