Scared to get pregnant again

Since losing my baby boy on the 6th October I am very scared to get pregnant once again as I keep thinking that this situation might repete itself once again and yes I know it's early to think of getting pregnant again but I can't seam to stop the guilt that is in my heart and my husband really loves kids and he was extremely happy when we found out about our boy that was taken from us so soon and I really want to give him a baby but I'm so scared to think this could happen again
