Who had completely different pregnancy symptoms with their successful pregnancy vs one that ended in miscarriage?

In March I miscarried at 9 weeks. It was my first pregnancy. I found out I was pregnant at 4 weeks and had menstrual type cramping everyday until 6-7 weeks. I was always very nauseated and my boobs were extremely sore (these are typically normal pregnancy symptoms). I felt very confident that everything would be ok bc I definitely felt pregnant.. Then I miscarried. I am now 5+2 and my boobs barely hurt, I am not nauseated and have absolutely no cramping. My hcg levels last weeks were 2283 and the almost 4000 two days later. My doctors office has not called me so I assume this is normal. I am very fatigued but that's really my only pregnancy symptom. In a way, I am very happy that this pregnancy is totally different than the one that ended in miscarriage, but I am nervous as well bc I just don't really feel pregnant. Anyone else experience something similar?
