L., I'm so sorry for your problems. Good advice has been given to you. Isn't it amazing that the teenager can get pregnant without trying very at all but as we get our acts together and we really want a family it seems to be a great challenge to find the time, co-ordinate it with our cycle, eat properly, take the right vitamins and everything else we have done to become pregnant and stay pregnant.
The advice has been given to get a second opinion, I agree.
The advice has been given to have a second D&C, I agree. Retained products would mean the first D&C was not complete! you may have a case against the physician, along with the fact he never took your hormone levels. I use to be a nurse that worked maternity, one of the happiest and can be saddest departments to work.
The advice has been given to give yourself some time to heal, physically and emotionally at this point, I agree. Your body must be at it's peak of health to be the best place for your baby to begin life. Give yourself some time. These days 32 is not too old, my age is too old, 50 for more than one reason. Get back on your feet after seeing another doctor or two. Remember you are the consumer and if you don't like the product in one store you go to another, shop around til you find the right fit.
Lastly, seek God in this time of apparent tragedy. He gives us struggles to strengthen us to become more like Him and to rely on Him for everything. You have received a message where you will be prayed for, I agree and will keep you in my prayers.
Would love to hear when things get better for you.
