do I need fertility help?

Jo
Ok so I have 2 kids.  Both high risk pregnancies.  One premie and the other late.  Both with complications and I hemmeraged.  I was told I couldn't have children but had 2.  Since then I have had 2 miscarriages.  I'm 35 now and trying to conceive again.  Not sure if I should look into getting help. Do I need fertility help?
