@Patience86 have you seen dr m or another immune reproductive specialist? I'm not sure but I don't think clexane and aspirin alone Wd help. They thin the blood, whereas the prednisolone lowers the immune. Have you looked into neupogen or ivig or intralipids? They all act on the immune system so might be able to help. I really think you need to see an immune dr that specializes in pregnancy as well as immune stuff.
Good luck and I am so sorry for your loss.
