5th month of Accutane, should I get a tattoo?

I'm in my 5th month of Accutane and want to get a tattoo on my shoulder. I weigh 73kg and take 40mg twice a day. Can I safely get a tattoo now, or should I wait until the beginning of March (four months after I quit taking Accutane)? The only side effects I experience at this point are bloody nose and fragile epidermis (as in, if I bump against something, I get shallow scrapes but no blood).
