6 weeks HCG Blood Draw

Ive been doing blood test’s for HCG for the past 3 weeks, the last 2 weeks were good (480 on 16 Jan -4w & 4,170 on 24 Jan -5w) but my doctor called me today for this weeks one (it was 12,200 on 30 Feb -6w)

She said it should be a little higher but it still looks pretty healthy and she will be able to confirm with my ultrasound results on this Monday 5th February

What were your levels at 6 weeks? I am a little worried but I’ve started getting morning sickness this week which was reassuring but now I’m confused
