Had my appointment yesterday

I had my 14 week appointment yesterday. Everything seemed good, heartbeat was 156. I am high risk so I got referred to a high risk specialist. At first they said they couldn't see me until the middle of September but would reevaluate when they got all my records. Once I got home I got a call from them saying they need to see me next week. So now I am going in on Tuesday. Should I be worried they want to see me so soon? I know it's good to keep baby monitored and everything but they didn't rush things like this with my first born. I didn't go see them until 20 weeks. It's kinda freaking me out lol.
