hi alfies mum,
I have also had 4 miscarriages, 3 in the past 12 months and have 1 healthy little boy. There are apparently lots of things that can help, but it depends if there are any underlying problem. My FS sent me for a saline ultrasound, which found a uterine polyp, but you can also have a whole heap of blood tests to rule various things out. Are you seeing a Fertility specialist? You can get a referal from any GP. If you google recurrent miscarriage, there are a number of interesting studies that might help?
GL!
