I had a PE while pregnant with my eldest child, had 6 months of warfarin after being induced 2 weeks early and was told that any future pregnancies I would have to be injected with clexane daily (reacted badly to fragmin). Had healthy pregnancy with my daughter and had the daily injections which I did myself though my mum took great pleasure in doing them for me while I was feeling ill and unable to do them myself and again, was induced 2 weeks early to avoid spontanious labour, had a safe natural deliery and am NTNP to do it all over again! The daily jabs do suck and yes they are sore, but it is all worth it to be healthy and there to raise your child(ren). My top tip though, have an ice cube to hand and rub it over the jab site after you've jabbed yourself, it doesn't hurt as much! :-D
Much love x
