Hi!
Unfortunately, greater than 50% of viable pregnancies will have a heartbeat at 6 weeks. It is NOT 100% though, so there is still a chance. With the exception of the missing heartbeat, your ultrasound was perfect. It is common to be off by a week or two.
A couple of things you could do if you want results sooner than next week.
You could have your pregnancy hormone levels (beta HCG) tested to see if it is rising.
And you could have a progesterone level done. A falling beta HCG or a progesterone level of less than 10 are bad signs.
I hope this helps, and I hope your OB is wrong. I actually prefer to be wrong in a case like yours--I love to hear "I told you so" I hope you get to say it!
Good luck!

I know that usually you can't hear a heart beat at 8.5 weeks but from all the books I've read and research I've done you should be able to see a heart beat at this time. Plus the fact that my uterus, bladder, and all that was measuring at 8.5 weeks but the baby was not was what really scared me. I'm trying to prepare for the worst in case my appointment on Thursday shows no growth or heart beat but there is still this hope inside me. I've had pretty normal pregnancy symptoms up until the appt. Then after I started having lower back pain that went through my leg which I'm afraid is a sign of miscarriage. Strange that I didn't have this till after my appointment though. I wonder if the ultra sound triggered the miscarriage? Some times I feel okay with this and some times I break down crying. Its all I can think about even though I'm trying not to stress about it.
The only thing I keep thinking is that when you do miscarry this early its due to a chromosomal abnormality and there was nothing I did wrong. While I would be very sad to loose this baby I'd prefer that my baby be healthy and happy. I've also heard that after having one miscarriage that you have a 70% chance of getting pregnant again and that most pregnancies after a miscarriage go on to be normal and healthy. I hope this helps some and good luck to everyone. I will keep looking on here to see what everyone else ends up doing.
