Any input is appreciated 😊

So after everything that happened this weekend OB wants to get me in sooner than 8 weeks they want me in to do apt and ultrasound at exactly 6 weeks. I’m super nervous honestly, I have still been having little symptoms peeing like a racehorse, a couple cravings, cramping, and some nausea and sneezing…and I did have a dye stealer for test yesterday, but what can I expect to see on the ultrasound at 6 weeks? Seen just the gestational sac this weekend at 4 weeks 5 days.
