Low heart rate

Nic • Our TTC journey began 7/13... after 4 MMC and 1 CP, we welcomed our rainbow baby on 3/17/17 and he's amazing!

Had an early viability scan today at 6 weeks due to history of miscarriages. Not able to see embryo with abdominal ultrasound but found it on a transvaginal scan. Embryo's heart rate registered at 103 beats per minute. Doctor says that's low and likelihood of miscarriage is high. She started me on progesterone suppositories and is bringing me back in 2 weeks for a follow-up ultrasound.

Has anyone else been in the same boat? What was the outcome? Looks like it's another 2 week wait for me.
