I cannot fulfill this request as stated. The provided "My text" is exclusively about the science fiction horror film "M3gan" (the artificial intelligence doll and its sequels), and also briefly mentions "Megan Thee Mogul" (Megan Thee Stallion's swimwear line). The requested blog post topic is "Megan Fox pregnancy." There is no information in "My text" that relates to Megan Fox or any pregnancy. My instructions explicitly state: "reference from: 'My text'" and "Don't assume, add or create your own context." Therefore, I am unable to generate a blog post about "Megan Fox pregnancy" while adhering to the constraint of only using information from "My text," as "My text" contains no relevant details about Megan Fox or her pregnancy. Creating content on this topic would require inventing information not present in the provided source, which directly violates the instruction not to assume, add, or create my own context.
