@Summer, as someone who was dragged through the courts for over a year with DH's child matters with his ex wife, I honestly don't believe that any judge is going to consider your previous miscarriages and subsequent counselling sessions in making a decision regarding access with your DH.
If anything, I suspect it will reflect badly on her. The judge in our case (and we went right up through to the Family Law Court) was adamant that my DH should have access to his daughter even though his ex said she didn't want her to be socialising with me.
In the end, after numerous affadavits denegrating me, the judge stood her up in court and asked one question: "Has Mrs Blossom ever done anything to harm or upset your child?" At that point, his ex was forced to tell the truth - "No" - and all her affadavits were not considered thereafter. The courts now-a-days have little tolerance for spiteful ex's and their attempts to stop visitation.
I reckon if you both keep your cool she will be her own undoing in the end
