Hello everyone my mother had three miscarriages and thre living children and 1 still born (her first pregnancy at. 40 weeks and 2 days)
My mother in law has also had a still born her first baby.. And has two living children. 
Both of them were due to uterus issues not being strong enough or something..
My first pregnancy was ended I miscarriage and now I am fearful of it ending in a stillbirth I am 17 weeks and I worry always... Is it more likely I'll have one since they both have?
