Choose "Yes" for fertile period if you want to be impregnated after creampie, this leads to a branching stage after finishing the third dungeon where you oversee Kanami in the hospital preparing for childbirth.do i choose yes or no for the fertile period? like what does it change?
important to note that this hospitalization event took quite a long game time, so if you want to just have sex without getting pregnant, you can choose "no" for the fertile period
