jennifr--I went to MGH for my care, and the thing with having an appt before 8 weeks is that can't really tell you anything about the health of your baby at that point unless you get an ultrasound. And early ultrasound isn't really indicated for most patients. A doppler doesn't work until 10-12 weeks or so (depends on the mom's size and where the baby is hanging out).
However, if you have questions about what meds are safe to use during pregnancy, don't wait to ask them! Call the OB office number (724-BABY) during business hours, say you are a patient of Dr. So-and-so, and ask your question. A nurse will look into it and call you back. (She will consult your doctor if necessary).
ALso, MGH does most of the patient education about pregnancy safety/guidelines during the nurse phone call, not the first OB visit. THe nurse phone call is typically scheduled a bit earlier than the first OB visit.
If you have a history of miscarriage and would like an earlier ultrasound, call the OB office number and ask to talk to your doctor or her nurse about whether you might be able to get an earlier ultrasound, while explaining your concerns and medical history. My MGH OB was able to schedule an ultrasound before my first appointment due to my prior miscarriage. (She was clear that this was for my own peace of mind and not medically required, but I was glad to have it. And it turned out to be very important medically in my 2nd pregnancy, but no one could have predicted that....)
Anyway, you won't see your OB at the ultrasound appointment, but you will get to talk to the OB or midwife who is covering the ultrasound that day and they will advise you on whether things look good. Typically this is done around 7 weeks or so, when they can expect to see a heartbeat and get a sign of whether things look healhty.
Overall, I was pleased with my experience at MGH, and I was glad I got my care there!
