The highly sensitive uterus

I was driving home today after dropping my son off at school and thinking of all the people who have asked me what caused me to have a premature birth.  I laughed, as I thought to myself,  I was told the reason for Joseph's premature birth was because I had a extremely sensitive uterus.  This makes me laugh to the point of almost pissing myself because recently I was sitting in front of a dear friend who was giving me advise and recommended that I read the book "The highly sensitive person".  Well, I suppose if I'm a highly sensitive person, it goes without saying that I would have a highly sensitive uterus. You just have to laugh...
