So sorry for your loss. We had 3 losses before our DS was born. The first was at 9 weeks and they found out afterwards my rubella immunization was low, so we waited three months. The second was at 12 weeks and I fell pregnant the cycle after the D&c but lost bubba at 6 weeks. I then fell pregnant again the next cycle and it was with DS. Should probably add that my cycles were very irregular - between 50-78 days.
I think a big part of it is being emotionally ready. Good luck
