I'm so sorry for your losses.
I know how you feel right now. It's really hard having to go through this. My advise would be take one day at a time. First recover from your D&C, and then try for a BFP, and then when you are pg again, just let your feelings happen. You maybe fearful and sad one day, and happy about the BFP the next day. Which is pefectly OK. Don't deny your feelings, just accept them. It's OK to be fearful, but it's also OK to be hopeful at the same time.
I hope you have a very uneventful PG in the near future. Good luck and again
