Could it be twins?!

Sarah

Hi all - I’m 5 weeks today. just got my HCG levels over the last week with these results:

2/13 - 427

2/15 - 1,298

2/19 - 11,395 (today @ 5wks)

Progesterone was also 72.

I have had two previous miscarriages and have previously experienced slow rising levels but never big jumps like this…has anyone had more than doubling every 48 hrs? What was the outcome? Twins?
