I'm 6 weeks as of today?

So I'm currently 6weeks right now but I don't have any nausea or nothing just fatigue headaches and cramping but the cramping is also calming down I went to the hospital to get a blood test when I was 4w4d my hcg levels were 1200. Idk maybe I'm just super nervous about my first gynecologist appointment on the 23rd and hearing my babies first beat and to see if it's truly there or if it has one I pray everything goes smoothly but has anyone ever felt like this I'm so scared of miscarriage I'm scared to do a U thing I work as a CNA I refuse to sped down the halls and rolls patients and lift them I take it extra slow this is my first also I'm just nervous
