hey Crys,
Have you been given any reason for your infertility or is it an unexplained case?
I don't know if you have ever heard of Maca, but I recommend anyone with infertility problems to give it a go (both the male and female), I have seen so many people have success with it and the best part of all is it is a totally natural supplement.
More info here:
Using Maca to Boost Your Fertility
For a lot of people fertility does return with weight loss and a healthy eating regime (sometimes it isn't quite as simple as losing weight, it can be the types of foods you are eating too, heavily processed stuff being a no no and for that reason Slimming World is a fab diet to recommend to anyone). But of course it depends on what the cause of the infertility is. Being overweight can affect your hormonal balance, and eating unhealthily i.e. lots of processed/fatty foods can cause lots of toxins etc in the body.
I really feel for you. It must be such a hard journey for you, 10 years is a long time and infertility is hard on anyone.
All I can say is Slimming World is fab, because it doesn't just help you lose weight, but it really does help retrain our brains to the way we look at food.
I am sure you will get there. Good luck!!
EDIT: Just seen you have PCOS, I would definately recommend trying Maca for anyone with PCOS. Also, have you ever been prescribed metformin?
So sorry to hear you have experienced 3 miscarriages too. Any loss is heartbreaking

, did they do any investigations into the recurrent miscarriages? Like the karyotype testing and also looking to see if you might have Thrombophilia? Feel free to message me if you want to chat to somebody and that goes for anybody else on here too. I did a lot of research (read far too many books etc) when I experienced infertility myself and may be able to offer suggestions that you havent you looked at/tried.
