Anxious and lots of questions

Kiersten
I keep posting on here but I haven't told anyone that I'm pregnant and this app has been beyond helpful in answering my questions. So I'm 4 weeks pregnant and my doctor won't see me until almost 12 weeks 😳. I've had several friends miscarry and it makes me so nervous to wait that long. Do you think my primary care doctor would get me in for a blood draw around eight weeks? Am I over reacting? It would just be so devastating to wait that long for an ultrasound to not find anything. I'd rather do blood work earlier. What were your experiences with how long the doctor made you wait for your first ultrasound?
