I'm not sure specifically as I haven't read that particular fanfic. It could be about Betty's experience during childbirth, perhaps the emotions she goes through, the people around her at that time, and how it changes her life.
I'm sorry I can't really recommend similar fanfics as I don't know the exact nature of the 'betty gives birth fanfic'. But you could try searching on fanfic platforms using tags related to pregnancy, childbirth, and the name Betty if there are any.
Obviously, Ana herself would be the central character. Her partner could be an important character too, being there for her during the pregnancy and birth. Maybe her mother or a close female friend who offers advice and support.
The fanfic might focus on the actual birth. It could describe the setting, whether it's in a hospital or at home. And also the people around her during the birth, such as a midwife or her partner. There could be some tense moments and then the joy of the new life arriving.
Well, it could be about the challenges Clary faces during childbirth, like her fear and the support she gets from her friends. Maybe her partner is by her side, holding her hand through the pain.
It could be a mortal man who somehow managed to catch Artemis's eye. Maybe he was a great hunter like her, and their brief encounter led to the pregnancy.
One common theme could be the development of family relationships. When the reader gives birth, it often leads to the exploration of how the new family dynamic works, like the relationship between the reader and the partner in the fanfic, and also how they raise the child together.
There's also the possibility that it's an unknown stallion from a far - off land. Twilight could have had an adventure in a different region and met someone there. This would add an element of mystery to the fanfic, as the readers would be curious to learn more about the father's background and how he and Twilight met.
Obviously, Prowl would be the main character. There could also be her partner, if she has one. Maybe a friend or a family member like her mother or sister if that applies in the story's context.
The fanfic might focus on the emotional aspect of Prowl's pregnancy. She could be feeling a mix of excitement and fear. As she gives birth, it could be a moment of great joy and relief. And perhaps there are some challenges during the labor that she has to overcome.
