How soon is too soon?

Megan

I miscarried a couple weeks before christmas. I have had my period since then and am thinking about ttc again. From what my husband has said I believe he wants to try ASAP and or as soon as I'm ready. I still get sad sometimes and cry over losing our baby but I dont know if that will ever really go away. We have a toddler and want him close in age to his sibling. But is it too soon? How do you ever really know?
