Source of Life,
With joy and celebration,
With hope and gratitude,
With care and caution,
Knowing the risks and challenges ahead,
I/We pause to give thanks
For this pregnancy,
This potential for new life.
Grant my doctors wisdom
And my body strength
So that I may know the holiness and wonder,
The radiance and light,
Of carrying life and giving birth,
And the joy of motherhood.
God of love,
Grant me/us [this child/these children]
In the fullness of health,
In the fullness of joy,
The gift of generations,
A gift of glory beyond measure.

Praying for a safe, happy, and successful pregnancy and birth, and for the health of my wife and both our girls. I would be incredibly grateful if you joined me in that prayer.
