recurrent losses.. any success stories?

Since Feb 2017 I've had 4 miscarriages. 2 mm, 1 blighted ovum and just this month a chemical pregnancy. it's hard to keep hope alive sometimes. I do have a healthy beautiful 3 year old and he's what keeps me going. I'm also 37. should I throw in the title? any success stories after so many losses and at my age? I feel like I'm raising the clock and fighting a losing battle. thanks in advance.
