am I over reacting

Amanda • I'm a mommy to a bueatful 3yr old baby girl who is begging to become a big sister💕❤
So I asked my fiancé if he wanted to be with me at the doctors when I get blood work done the ultrasound and all n he told me no .. I'm only 6 weeks pregnant but I am an emotional reck this just hurts what if he never comes to a doc appt with me?
