tattoos and ttc

Is it okay to get a tattoo while TTC? I'm not pregnant, but am TTC.  I just got off birth control last week. Next week is supposed to be my fertile ovulating week. My boyfriend and I had wanted to get tattoos this weekend but had to reschedule to next week and I am concerned if it will affect my fertile window. I can't really see why it would but I just want some reassurance as to whether or not I should go through with it! Thank you
