6w4d ultrasound

So last week I had an ultrasound at 5w4d, 2 sacs were seen but one was way too tiny to be diagnosed with twins.. my levels were 3617 this day. Well today I went for a repeat ultrasound and both sacs grew, the smallest one still completely empty and the second was a 9mm gestational sac with visible yolk sac, my levels are now 6527.. my question is did anyone have a similar experience? My levels took 7 days to nearly double, but both sacs grew and one with a yolk sac..? I have a repeat on Tuesday, but expecting the worst
