Had first OB appointment, confused and nervous.

Had my first ultrasound and exam today. By my app, I was supposed to be 7 weeks 1 day pregnant, however, they are thinking I’m a lot at earlier.

The ultrasound showed a gestational sac and yolk sac, no baby. They are keeping a close eye on me, I had blood work done, and going back again Friday for my blood work , and next week for another ultrasound.

It’s kinda starting to make sense to me now. My app said I ovulated September 28 (first day of my last period was September 11), and we hadn’t had sex around that time, however, I think I ovulated around October 5th (sex no withdraw that day). So that would put me at 5 weeks 6 days give or take.

Does that sound right to anyone? Trying not to stress much.

Thanks!
