Blood thinning before a tattoo?

I eat garlic and I take multivitamin pills containing vitamin E on a daily basis. Both are considered to have blood thinning properties. I have heard that you shouldn’t take blood thinners if you are getting a tattoo (I’m not taking any blood thinning medications). The last time I ate garlic was last Friday (3 days ago) and the last time I took a multivitamin containing vitamin E was yesterday. I want to get my tattoo done this Friday (in 4 days). Am I safe to get it? Is the blood thinning of garlic and vitamin E not significant enough to cause problems during a tattoo?
