My heart goes out to her and I reflect how G-d shows us over and over again how we are not in control. Conceiving, pregnancy, birth-like everything in life, but more so in this process, is the time to let go-relinquish control and realize that we are not in control. It's not the medicines, it's not the doctors-we are all just messengers from Above., it's G-d. Pure and simple. He decides, how, when, and where.
But yes I tell her, it will happen.
