That's okay! You can edit the story lines however you need to! The options are more to help with a general outline, they don't have to be the whole story! For example, for option 1 your couple could decide to use a surrogate (a sister, friend, stranger, or whatever!) but there were some fertility problems and it took longer than expected, or you could just say they did it and ended up with triplets! Option 2 would be the only one that wouldn't quite work, but you can change it around any way you want to make it work! :)
