Hi,
So sorry to hear of your losses. I had to have IVF/ICSI to conceive for what was thought to be only Male Factor Infertility. I had 6 miscarriages throughout that time and after the 4th one I had immune bloods taken which were known as Chicago Tests. They came back to show that I had elevated NK Cells, Factor V Leiden & MTHFR Gene mutation (homozygous).
I had another 2 cycles of IVF - with Clexane Injections, Progesterone, High Dose Folic acid and Prednisolone steroids.
That mix of drugs on top of my IVF gave me a beautiful little boy who is now 13!
Have you read the book by Dr Beer? 'Is your body baby friendly? Unexplained Infertility, Miscarriage...' it's a very good book and super informative with lots of info about steroids.
I'll be honest, I found the steroids tough going, not as tough as repeatedly losing babies but still difficult. I had trouble sleeping, but trouble staying awake, they also gave me a face like Rik Mayal in drop dead fred when he gets his head stuck in the fridge but they worked. On top of the other drugs involved in my protocol of course.
Personally, in your shoes, I would get the book and research your options.
I wish you the very best of luck.
