My experience is similar to Mary's . For the site of the injection made a difference as well, my thighs bled more than the other sites.
Mary's tip to pull the needle straight out and don't remove it too quickly.

Many times nothing, most times just a drop (clear, not blood), a few times a quarter size on tissue and once there was a gusher. You may be removing the needle too quickly after injecting. I do a casual count to ten once the injector is finished and then hold gentle pressure at the site for several seconds after removing the needle (straight out).
