You might find it hard finding a tattooist to do it, most have a policy against it.

I also thought piercings/tattoos weren't recommended during pregnancy because your body can react to it differently and heal differently because of the added hormones or something?

Personally I wouldn't while I was pregnant, I guess for me it's one of those added risks that can wait until after the baby is born.
:yeahthat: I was told by a tattooist that she wouldn't do it because there's a (albeit small) risk of blood poisoning. The risk is low and applies to everyone, but if you're pregnant, that risk affects the baby. I think you'll have difficulty getting a tattooist to do it if they know you're UTD.
