As far as I remember, Zorlun stated that he wasn't a big fan of tattoos. So that seems unlikely. But even if he does introduce them, it will only happen near the end of the game, so don't get too excited.
And why do people keep asking about pregnancy all the time? It should be obvious to anyone who gives this any thought at all, that you can't have an optional choice for Myriam to get pregnant, without creating a ton of extra work for the Dev, who would have to make every scene with Myriam pregnant and not pregnant. This is why pregnancy rarely features in adult games, unless they start out with that intended to be a specific part of the game.
