A little anxious and fearful

You'd think I'd be happy, but no I have a heavy heart full of fear..

My fiance and I have been together 9 yrs in August two misscarriages and now I'm 15+2 and I still fear I'm gonna lose the baby..

I've seen him/her and heard the heart beat at 14 week's! But apart of me is afraid to bond. I'm afraid to talk to my belly..

The heartache of another lose would send me into an ultimate depression and I feel alone cause me fiance tells me not to think of it and to remain positive.

No matter how much I try to remain optimistic I find myself constantly afraid..

I like many other's have wanted nothing more than to be a mother, with early losses.

How can I rid myself of the worry and fear?
