I don't want to see the main character get pregnant; nor do I want to see her date a guy. I prefer male swapped to female characters to experience yuri. If there's no yuri, then I'll settle for ecchi, with no males involved. If I can't have that, then I'll settle for comedy stemming from the main character being a different sex and adjusting to life
But this pregnancy foreshadowing worries me that the story is now going to introduce a male love interest for Junpei. When I see a gender swap tag, I look to see if there is also a girl's love tag too. If there is no girl's love tag, then I make sure there is no romance tag present. Because if there is a romance tag, it mean male and female romance. The thing about tags, is that they can get added later on as the story progresses. The only time I'm interested in a male and female romance in a gender swap story, is when the male and female characters are both swapped. Either a body swap or they both swapped their sexes. Just a personal preference though. No shade on anyone that feels different.
The pregnancy foreshadowing may also be a red herring. Since Junpei was also introduced to lesbian sex in this chapter. The author could take it in either direction.
