Not sure what to think

According to my last period, I am 8 weeks pregnant today. The ultrasound today showed 6 weeks and 3 days and a heart rate of 89 bpm. Last weeks scan showed two sacs, one heartbeat and measured 6 weeks 1 day. So according to the scan today baby has grown 2 days over a weeks time? I’m so confused and not sure how to feel
