Pregnancy after miscarriage

Bi

Just found out I’m expecting after having a miscarriage last month. I’m super nervous. Would it be over reacting to call my doctor and ask for blood work? They usually don’t see their patients until between 8 to 10 weeks. I hadn’t seen the doctor when I miscarried last time at 6 weeks. I see a lot of women on here getting their hcg numbers checked. Did you have to ask for it? I think it would put my mind at ease to know things are doing what they are supposed to. I just can’t relax 😭
