Almost 6 weeks pregnant and...

... I'm not getting an ultrasound until 8. Which is normal I think but I am a nervous wreck because I just want to know my baby is ok. Like nothing is wrong. I feel normal, just tired and slightly pukey in the mornings. But I want to know the baby is doing alright and I have no way of knowing and it's killing me.

Probably does help that I lift every day at my job. Only 30lbs but I am a first time mom and every time I lift something I get a wave of panic that I am doing something wrong.

How do I know the baby is safe before my ultrasound?
