So long story short I had to perform a blood self extraction on myself, which I have not done before. It was meant to be a take home fingerprick test but I had no luck milking out any blood on several fingers. I swabbed (with alcohol pad), went in (31g 4mm) for the hand vein, aspirated and missed, then without thinking about it I swabbed one of the veins in the nook of my arm, and went in with the same needle, then drew a ml of blood. Any chance I introduced bacteria into my blood? I'm thinking something I aspirated, or that lives on the skin and is normally harmless.
