Hi. I am using heparine in my pregnancy (6,5 months now). It took me a while to find out where I best could inject without getting bruises (upper thigh) but since then, injecting is no problem. In the last week however I get awful bruises, quite big. Is this an indication something happened with my blood, or is it bad luck I just keep hitting small blood vessels? I have an appointment over 7 days with the hospital but am wondering if I should contact them earlier about this. Anyone having similar experiences and can explain why this is happening?
