How is childbirth handled?

Recently I decided I wanted my character to get pregnant and have a baby. She’s in a sense “dating” another PC in our group. I have talked to my DM, and we’re trying to find out what’s needed for when the baby is born. I already know at one point my character will be a bit incapacitated and I will have to wait X months in game time before the baby will even arrive.

The real questions I have are: is there anything I need to roll for, and if so what stuff will I need to roll? What stuff do I have to determine or does the DM need to determine, etc?
