Odds of M/C twice in a row.

Hey everyone here's my info
I'm 24, partner 27. 
We have a healthy 3 year old daughter who was conceived whilst on a week break of the pill.
we had mirena coil taken out for baby number 2 got pregnant after 2 months TTC. Unfortunately had a miscarriage late July at 5 weeks. 
My doctor has told me that 2 consecutive miscarriages happen in less then 8% of women and also for a woman who has had a live birth before miscarriage the odds drop to 5% does anybody have any positive stories about this? Xx
