sweet heart, dont count yourself out until its over ok!!!
Babies are miracles!!! could you have miscalcuated your ovulation date????

Put it this way, my last period with my children was WAYYYY off my due date, i am talking a good week or so!! last period really doesnt mean much, its when you ovulated that does.

In regards to the heart beat, a low heart beat isnt "ideal" but it also doesnt signal impending miscarriage hun, my neice had a HB of about 100... both my children sat and sitting on 140 BPM.
What was the babies heart beat?

When it comes to dating scans, the best time to have it done is 7-9 weeks. Any thing before that isnt as accurate as it can be... Scans are not accurate full stop! THey are always +/- a week and can even be up to a month out! it all depends on who is doing it and how good they are, even with the bestest of the bestest sonographer there is always a margin of error.

Sending all my love and hugs to you, and i hope you have the best possible outcome.
I will watch this thread for updates from you
