HI Keen,
It is scary isn't it? I turned myself inside during my last "viable" pregnancy worrying. As Michelle has mentioned I had a reaction - hives and pin point bruising unrelated to the injection site. This was with Clexane. I have just been on Fragmin and had no reaction at all so it is likely it's the suspension rather than the drug that was an issue.

As Michelle says Clexane has a short half life. It is not known to cross the placenta and the risks to the baby seem to be very very minimal (I say this because I can't really find any evidence of risk but I don't want to say a blanket no risk ).

I know from reading your posts Keen that your journey has been long and you are very learned but I just want to reiterate. Clexane appears to give women who recurrently miscarriage due to a clotting disorder AND or an autoimmune disorder the best chance of successful pregnancy outcome. Clexane also has a mild autoimmune effect. I think you are seeing the famous DR S??? Are you on prednisone as well or just the clexane?

Anyway I have digressed but just want to say from all I have learnt the effect to the baby is almost a non issue. as you know the affect to you is short term loss of bone density, obviously issues with bruising and bleeding should you be involved in an accident.

I am sending you lots of love and positivity for your latest journey Keen...
