TWINS!?! Based off pregnancy hormones

Beth
I need opinions! My nurse said based off my hormone level, I either have an extremely healthy pregnancy or I have more than one baby!!! Last Friday my levels were 174. Today my levels are 3,247.  I should be about 5 weeks 4 days medically. I conceived July 12 via IUI. I was on Gonal-F and Ovudrill.
