6 weeks pregnant

i went in for an early scan at 5 weeks, after i’ve had 4 mc. & they just saw the sac, they didn’t seem too worried.. they said it was just too early. or maybe i was earlier than 5 weeks. they guessed 3-4. they did blood work and there’s the results! what do u guys think? i’m extremely nervous, does your hcg still rise if it’s a nonviable pregnancy? (i hope that’s not the case! but i’ve been through so many losses and i don’t wanna get my hopes up) next appt is 12/21.
