7 + 1 and less morning sickness than this past week

I am 7 weeks 1 day, and today my morning sickness is less. I've been feeling awful this past week (nausea, extreme smell sensitivity, only eating bland foods). Now I'm worried something will go wrong (I miscarried around this time in August, but I had been spotting for over a week then). My boobs aren't as sore as they have been.

Ugh! Im just stressed and nervous I won't make it to the first ultrasound this Wednesday (my birthday!). Having a hard time staying sane.
