Nervous...

I'm 5w6d, had my first ultrasound yesterday and they saw the gestational sac and yolk sac, possibly a fetal pole but didn't want to measure because they didn't think it would be accurate. They said I may be a couple days off and could be earlier than I thought, so that made me nervous. Didn't see a heart beat yet. I had started getting nausea a couple days ago, and haven't felt it one bit today. My hcg was rising appropriately and yesterday they said it was looking good but didn't give me a number.

Now I'm just nervous that maybe the baby has stopped growing. I know there's nothing I could do about it if that's what happened but I can't help the thoughts get into my head.

I had a 21 week loss in April, and a 6 week miscarriage in September so I just can't help but be worried. Am I worrying for nothing or does it sound like something could be off?

Here's the pic from my ultrasound.
