Myth, myth, myth! (for the love of God how do these things get started?!) The ink from a tattoo permeates the third layer of skin--that's it! It does not affect the uterus, and there's no chance of becoming infertile from a tattoo. As for the stretching during pregnancy, well, yea, it's not going to look too pretty. You're tattoo will most likely be stretched out and will possibly be crooked after pregnancy. Most tattoo artists would suggest waiting until after childbirth to have ink done. Good luck with it!
