Another plot could be that Charlie and Harry are working on a special project together. During this time, they fall in love and Charlie gets pregnant.

Or maybe Charlie discovers that Jeep has a hidden talent, like singing, and they enter a talent show together.
Perhaps a plot twist could be that the Ministry of Magic tries to interfere with Harry's pregnancy because they fear the implications it might have on the wizarding society.

This would not only create a lot of drama but also show the strength of their relationship and their determination to protect their family.
