Many couples may relate to this story, @graat. The desire to have a child is strong, and yet it can interfere with the relationship of a couple as pressure mounts. You describe Rita's anxiety well. When she goes to the lab her apprehension, and anticipation are great. It seems from your description that Kenneth is not only happy at the news but also relieved the time of stress is over. Although, the couple will be facing new challenges with a child coming.
Your arc is strong as is your characterization of Rita. She is quite believable.
Thank you for sharing this story with us.
Thanks for your encouragement, it means a lot coming from you.
Thanks for the prompt too, pushing me to unleash the ink in my pen.
