Quoting kelsey gilmer:" I lost my daughter Savannah last week i had her at 38 weeks and she only lived 6 days i want to start trying eventually so but i dont when would be the right time."
The right time is when you feel like it is. When you feel like you have grieved. Not necessarily get Closure, because I don't think there is such a thing as closure after losing a child, but at least to when you can think about her without wanting to curl into a ball and cry until you vomit...
I am so so so sorry for your loss. Give yourself time.
Wish you the best.
