Dina hesitated a lot as she wondered if she should tell him the truth or not. After a minute of struggling with her inner thoughts, in the end, she finally decided to tell him anyway.
She couldn't find any good reason to hide this from anyone. She thought it was better to let the whole world know that she's already pregnant. Anyway, in a couple of months, her tummy would grow and everyone would come to know about her pregnancy sooner or later.
Also, if Adrian decided not to come home for more than a few months then they might think that the baby does not belong to him and someone else. It would become even more difficult to prove that it was his baby.
Since they did not consummate their marriage yet, they might point their fingers at her and could even torture her with gossips.
