Twins?!

So I had an <a href="https://glowing.com/glow-fertility-program">IUI</a> with 3 follicles and got my second beta back today

First beta HCG was

12/23 was 26 (10 DPO) (Progesterone was 38.7)

Today 12/26 was 201 (13 DPO) (Progesterone 47.5)

What are the odds more than one follicle made it?

With my last baby my levels were 102 at 12 DPO
