I forgot which city, if my memory is correct you did a quest to get ore for alchemist in a big city(capital?) before visiting next town, in that town you arrived in a park-like space and you will see an NPC with red event text on him near you, talk to him he will sell you a stone with 30K but still give you even you refuse to pay, then you go back to find alchemist who is inside a shop and a big red stone will appear, touch it and you can get quick pregnancy, you actually can preggy before this but it wont have any different except your doctor said you are pregnant, because it will take nearly 10 month to delivery (which means no effect in game) but shorten to less than 10 days with that stoneHow do I unlock pregnancy ? I already progress to the 2nd town with the doctor but can't seem to get pregnant anyway ?
