Sorry for your loss
I am no expert but I don't think you would have o yet. How long since your m/c? It may be your hormone levels affecting your temps. Temps are funny things as the slightest thing can affect our body temp so it is not always an accurate judge of when we o. Try not to be disheartened, I'm sure you are still in with a chance.
I am on the 2nd cycle since my D&C and I am pretty sure I am o now.
Best of luck!
