there's actual pregnancy, an actual belly and actual birth
but the chance to get preggo is kinda low even if u spam those ovulation inducing meds+fertility prayer, i didn't even know there's an acce to ensure it.
the belly is just a standing image of enicia having a preggo belly that is shown when u trigger a birth, and u can only access it after main quest clear and doing another smol quest to remodel the orphanage
the kid wud be shown in the newly remodeled orphanage basement after birth and u can view who is their father
