Twins?

I went into the doctor today for an early ultrasound to make sure everything is going alright.. ive had miscarriages before. My HCG levels are at 5254. And this is my ultrasound... could I be having twins? I'm 5 weeks, 4 days. I'm a twin and twins run pretty high in my family. Thoughts? I just can't stop looking at my ultrasound.
