One possible scenario in a Rachel and Mike pregnancy fanfiction could be that they accidentally find out they're having a baby while they are both focused on their Broadway careers. Maybe they initially panic, but then gradually come to terms with the idea as they realize they can support each other. They might start making plans for their future as a family, including how they will balance their work and family life.
One possible fanfiction could be where Mike and Rachel's pregnancy is a surprise to them. They might initially be scared but then slowly embrace the idea. They could start planning for the baby's future, with Mike being worried about his past affecting their child but Rachel reassuring him.
The plot might involve a twist where Rachel discovers she's pregnant, but she's not sure if Mike is the father. This creates a lot of internal conflict for her. She doesn't want to tell Mike right away until she's certain. Meanwhile, Mike starts noticing that Rachel is acting strange and becomes worried. As the story unfolds, they have to face the truth together and decide what to do about the pregnancy, whether they stay together or not depending on the paternity results.
They might also have to deal with changes in their work - life balance. With a baby on the way, they would need to figure out how to manage their time at the firm. Rachel, being ambitious, might struggle with the idea of taking time off, while Mike could be more focused on making sure they are financially stable for the baby. It could lead to some tense moments between them but also some really sweet reconciliations.
One great fanfiction could be where Mike and Rachel face challenges in raising their baby while also dealing with their careers. Maybe they have to balance a big case at Pearson Specter Litt with the needs of their newborn.
Some Tumblr blogs are dedicated to Suits fanfiction. You can search for tags related to Mike, Rachel, and their baby on Tumblr. However, the content on Tumblr can be a bit more scattered, so it might take some more time to find exactly what you're looking for.
It's possible that Rachel and Will are characters from a less - known or niche media. They could be part of a small - scale web series or a local theater production that has a dedicated fan base. In the fanfiction, the writer may be expanding on the hinted - at relationship between them from the original source material and taking it in the direction of pregnancy, exploring how that would change their lives, their relationships with other characters, and their own personal growth.
Since I don't know the exact story, Rachel could be anyone. She could be a fictional character created for a novel, a real - life person that the storyteller knows personally, or just a name used in a parable.
