Ultrasound

Latasha • Had ectopic pregnancy of march 2010, had 3 miscarriages December 2012-march 2013 with drs help. Had a rainbow baby girl August 27, 2015 and currently pregnant again naturally. 👏🏻
So I have an ultrasound scheduled for January 9th & I'll be 6 weeks 3 days. Has anyone ever heard the heartbeat then or was it later?
