Welcome Kerri! I am so sorry for your loss. If the doctor does the early blood work and finds that your progesterone is low, supplementing it will definitely help. My sister had 3 m/c and when they added progesterone she had four successful pregnancies! I hope your outcome is just as good. Did they do any additional genetic testing after the D&C? Many times they find out a lot from having those tests done too.
My doctor recommended taking vitamins and folic acid daily. You'll be TTC before you know it. And, I hope your wait for your BFP is a short one! KUP!
If you need people to lean on, the ladies on this board are awesome! I've only been here a short time, but, they are really wonderful! Welcome again.
