HCG Levels?!

So I’ve been TTC after an ectopic last year and finally got my BFP. My period was late and was skeptical on testing because all I got were BFNs. Anywho. After my 2 BFP I decided to go get some blood work and an ultrasound because I would be considered “high risk”. My HCG level on Monday was at 800. They said I’m about 4 weeks and 3 days. They also said they think they saw what would be considered the gestational sac. Going back tomorrow (Wednesday). Hoping my levels double and everything is okay for me. . Anyone have any positivity to throw my way? I’d really appreciate it.

Thanks ! - Britt
