I am so sorry for your loss. I heard a heartbeat at week 7 on the ultrasound. The doc could not hear it at week 11, but showed the heart beating on the ultrasound, so I am hoping to hear it again at my week 15 checkup. You will be back here on the 1st trimester board again, it just takes time!
As someone who has had a loss, this is not at all helpful.
OP, I'm sorry for your loss.
