hcg levels

Ariel • Proud step-mom with a baby on the way after loss

I'm pregnant after a miscarriage so my doctor has been doing lots of blood work. my levels seem high, 61.5 after 3 weeks and 6 days, and then 350 at 4 weeks 2 days. my progesterone is at 25. Anyone gone through this before? Something I read said it may be a sign of multiples!!
