Should I Be Worried After I Accidentally Poked Myself Mildly With My Cat’s Used Insulin Needle?

I accidentally poked myself mildly with my cat’s used insulin needle. It was not deep but drew a little blood. I washed the area for about 30-60 seconds, put neosporin and a band aid on and ate a hard candy in case insulin was still on the needle. Should I be worried or do anything else?
