Twins??!!

So I took Clomid 150 mg and had three follicles growing. The doctor believed I would ovulate two. I got a bfp 9dpo, and my hcg levels between 72 hours went up 390% and said they were doubling every 30 hours. I’m about 5 weeks, and I don’t really feel sick or anything just tired and cramping on and off. What do you think the odds are for twins? Any similar stories?
