I'm so very sorry for your loss of Molly. Did you deliver at a hospital with a nicu ? At such an early gestational age it still might not have helped.
The OB I went to for 17+ years (and raved about) really dropped the ball in two of my pregnancies. I was so angry I didn't bother going back for the six week check-up. I was angry for a very long time.
It's going to take time for you to get past the anger, especially since your daughter died. I switched over to a mfm for the next pregnancy and it helped so much to have a doctor I trusted completely.
Please don't give up hope, your loss is still so recent.
