TMI topic maybe miscarriage and still born

So here goes this past 3 years I have been trying for baby number #2 with 4 miscarriages along the way the last one in January to say the least it's hard.. but I keep trying...

Then my friend found out she was pregnant also 3 miscarriages previous to this pregnancy but anyway she carried her baby I agreed to do baby shower so hard it was to agree it was a complicated pregnancy for her I was there every step of the way... then 4 days ago when she was 23 weeks pregnant she got very bad contractions her husband rang for an ambulance by time they arrived 5 mins later baby was born in his sack he was born sleeping....

My heart is breaking for my friend I am going to funeral in 2 days time to support her..

But since this has all happened I am so scared to keep trying for baby number #2 as I am so scared I will loose a baby late and end up delivering.. I have not said none of this to my partner .... but last night I said I couldn't imagine was (my friend is going threw to him) and he said yea thats why I don't want to have another 1 I know it will happen to us and I couldn't cope

I understand him and I no how scared I am now to keep trying...but i really want it... is it normal after being so close to friend that loses her baby at 23 weeks to be scared aswell ????
