First ultrasound

Had my first ultrasound today. Finally was able to look at my beta results. First draw was in the 200s and Wednesdays draw was in the 2000s. Has anyone had a big jump like that? Also was supposed to be 6 weeks 2 days but measured at 5 weeks and 3 days. Is it normal to go down a whole week?? But yolk sac and everything is there so they said everything is looking good. Also have a 5cm cyst on my left ovary. Has anyone had a cyst while pregnant??
