Base line hcg and sac

Rach

How much was ur base line HCG when u first found out ur pregnant! Does hcg tend to be higher when ur carrying twins?

My first 14dp5dt 241

16dp5dt 585

I went for my first ultra sound on 5 week and 1 day but doc said she cudnt see anything clearly! Faint 2 sacs were there but she is not sure!! It’s ok to not see anything that early right!
