What we can see on ultrasound so early in pregnancy

Breanna

My LMP was 02/11 so that would put me at 6wk 4 days today. I had a scan on Friday when I was 6wk 1 day and all they could see is the gestational sac. My dr wasn’t worried he said it could just still be to early or I ovulated late I know there’s some grey area this early on. I go for another scan Friday 04/01 but I’m just curious how many of you guys have experienced this any everything has been ok. Trying to relax and not over think things but it’s hard!
