irregular fetal pole means not normal or unhealthy, though having a heartbeat is good, baby is really underdeveloped if it has not grown in 6 weeks. i think it is a waiting game on waiting for it to all pass. im not sure if you could recuperate from this but i wish you the best of luck in case my opinion is wrong
from what I heard a fetal heartbeat under 90 is considered non viable... I hope its not the case but this does not sound good.
Sorry hun this doesn't sound good at all. I had a u/s at 10 weeks and the babies hb was 186 bpm.
