I had two ectopic last year lost a tube now I’m pregnant a freaking out over my lab work 🥺🥺

Went to dr thursday after multiple home test , no I haven’t missed my period yet it due on the 2nd, they gave my a ultrasound which didn’t show anything of course , then sent my out for blood work, which I have to get again Monday since my hospital lab is closed on sundays, my proestrogen is at 2.85 it’s never been this low, my hcg is at 21.9, I know im only around 3 weeks 5 days and it’s early but I just feel the same thing is going to happen as before, at the point where I don’t even wanna get pregnant and keep going through this.
