I had Clexane after my emergency CS with DD (but they missed a dose).

It is often dependent on the Dr's school of thinking and what risk factors are present for the patient as to whether or not they give it. Also, there was a BIG international shortage of Clexane recently so Dr's may have altered their pattern of thinking when it comes to giving Clexane. They did where I work... until there was also a Heparin shortage!!!
