I need a baby to fill my empty arms

I just can't stop thinking about the time that I lost my son @ 34 weeks due to preeclampsia. It was very very hard to believe that I am a mother without any child. I have many questions with no answer I don't know why its all happened to me but I know 'GOD has a reason'. its been 5 months but the whole-things are round through my mind again and again. my husband want to ttc again I also need a baby to fill my empty arms but I extremely scared every moment that I might lose another baby. GOD please bless me with children?!
