Worried

I'm 9 weeks 2 days pregnant. I've had 2 ultrasounds and we've seen baby's heart beat both times. Baby is measuring right on track. And heart rate was 170. I don't go again til 12 weeks. Today I felt decent so I'm freaked out. Like wondering if baby is ok. I worry alot so I hope everything is fine. How can you not worry through each appt. This is my first baby. Anyone felt like this and baby be good. I haven't had cramping or bleeding so everything should be fine right? Everyday you'll feel different I'm sure.
