I know you can get pg after a mc even before your next af would be due..

I had a blighted ovum with my first loss (2001) I took a while to fall pg again but went on to have another son.. I had another mc 10 months later but it was not a blighted ovum and have 2 more children since then as well

good luck with your journey to having a baby. I am also sorry for the loss of your precious one
