I am so sorry to hear of you loss of Ryan. I too lost an infant (she was 7.5 months when she passed) and it's probably the most difficult thing I've ever had to deal with. If you haven't already checked them out, you might want to check out the stilbirth or loss of an infant board. (((big hugs)))
As for your tatoo - I don't have any first hand experience... but I imagine it would be fine. Have you asked the tatoo artist? You might also consider giving your doctor's office a call rather than waiting another 2 weeks -- I would guess that they'd be able to answer your question over the phone.
