Hi,
I was on Clexane injections for the duration of my 2nd pg to help with my arthritis/blood flow. I had no reaction or long lasting effects. My son was born at 38 due to a low birth weight that was monitored from very early on. I dont think the clexane had anything to do with it as my 1st DS was also of low birthweight and born at 37 weeks and i was on no medication so i think it is just how i "cook" my babies.

Best of luck.
