I have very much experienced this urge, longing and physical craving for becoming pregnant when I started to enter the final phase before menopause. Unfortunately, I haven't met anyone who could (have) helped me to fulfil this strong urge (I would have been perfectly happy with just one pregnancy and child - but it has not happened) and some things presumably can't be forced. I'm gradually trying to become better about it.
I just wanted to say I very much relate to it. A tricky topic.
