Might be a dumb question..

Devynn • Momma of a 7 year old girl & a 4 year old little boy & currently expecting 🥰

So I went In to my 10 week & 6 day appointment and baby’s heart rate was 159. I went to the hospital this evening cause I was having some light red bleeding.. and they told me if that ever gappened to go be seen asap cause then I’d need the rhogam shot early.. so I got it today and all they did their work up I’m now 13 weeks and 1 day & the heart rate is 169. Is it normal

For it to fluctuate? I guess I know ours do but just trying to make sure and if anyone got their hcg levels back around this time what we’re yours?
