The ultrasound is the only thing that will let you know for sure. Currently in my 9th week with twins. The HCG levels were high for a singleon but that means absolutely nothing, the only giveaway is that in two days my levels quadrupled from 601 to 2495.Nothing could or should ever be confirmed until the ultrasound.
Even when the twins are confirmed new worries arise, will both make it my RE tells me every week not to be or get too excited even thoguh the heartbeats, thank god, are strong.

One child is a blessing, you love them all the same.

When I went in for pregnancy bloodwork on 17dpo, my HCG levels were 875 and 48 hours later they doubled. Even the nurse hinted it might be twins with such high HCG levels. We went in for my 6 weeks scan and there were two separate sacs (so fraternal). At that time, only one baby had a hb. Two weeks later, the next scan showed both babies had a hb but oen still had a lower hb and is measuring a little over a week behind. Hopefully, both babies make it.
I think sometimes (but not always) hcgs can tell because the nurse told me all the other girls who were having singletons had hcg of almost half of mine on 17dpo.

My first U/S that I saw the girls, I saw two completely seperate sacs thus fraternal sisters.  My numbers were not in the ten's of thousands at all either.  Don't go by the number but by the U/S.

Hi - My first early u/s (transvaginal) showed only one sac - it was empty - very early u/s.  My second a few weeks later with HCG at 84000 showed one sac - 2 Embryos so I am having Identical vs Fraternal.  Good luck hope you find out soon.  3 weeks is early to have anything inside the sac :)

An u/s shows 2 babies. That is the ONLY way to know. Numbers don't determine twins. I always had normal numbers for a singleton pregnancy and had twins.

If there was one sac and no indication of more than one heartbeat, you have one baby.
