FTM and not "feeling" pregnant

I have my ultrasound next week and I am very excited because lately I don't "feel" pregnant. My boobs are not that sore anymore and I don't have morning sickness. My only symptoms are fatigue and frequent peeing. Is anyone else feeling the same? This is my first pregnancy and I don't know what is normal. I hope baby is ok and still growing fine and I'm just worrying over nothing.
