Small gestational sac at 5W2D?

TW: Pregnant,

TMI photo.

Hi lovelies,

Went in to the ER yesterday after bleeding. They referred me to the EPU where I went in for a scan today. I thought I was at least 5W5D. All we saw today was a gestational sac, which measured 5W2D (5 mm). I have attached the photo. Does it seems ok to you? So nervous and anxious. They have called me again next week for another scan.

The only symptoms I have are mild back aches, tender breasts, and occasional nausea (not throwing up or anything, just weird feeling in my throat).
