I got a tattoo on friday just a small k on my wrist but i just today discovered im pregnant?

You going to be fine. What you need to do more than anything else is take care of your body. The tattoo, make sure it's always clean, and avoid an infection. The ink does not the skin deep enough to enter the blood stream, so the ink will not affect the baby. The reason artists don't tattoo pregnant women is because of infection and the very slight risk of disease. The chances of you contracting a disease due to a tattoo are slim to none. If you went to a shop an didn't get it done by a friend at their house, you're fine. Shops have very strict cleanliness guidelines, so your concern right now is keeping it lean and avoiding an infection. Infections can affect the baby, but, you should be safe since you got it Friday and have had no negative effects. Just keep it clean and take care of your body and you and your baby will be safe and sound. Congrats!!!!
