In brief: Probably not
A bruise in the area of the spot where blood was taken is frequently seen.
It occurs because the blood has leaked out into the surrounding tissues near the vein that was used. It occurs because there was not sufficient pressure put on the area for a long enough time for the blood to clot so it won't leak out. Or, you may have recently taken Aspirin and your blood does not want to clot quickly.

In brief: No
Sometimes there is bleeding around the site of a bood draw.
It will turn different colors while healing. The ecchymosis can be larger when donating blood because the needle is larger: 16 vs 23 gauge.
