I had my first m/c several years ago. I found out I had been pregnant by m/cing. I had at that time not decided that I would ever have children at all. It was not a good time in my life or relationship to have a baby. But oh did my arms ache all the time. Pregnant women made me cry, I had to physically restrain myself from picking up other people children.
There is a huge hormonal component to it, that for me faded with in a couple of months. Then I was able to deal with my desires, and not just my bodies'.
I am not saying it's not real, no one who has experienced could think that, it's almost too real, It's just that it does receed, and leave you in a better place to decide what your hearts desire is.
