They meet, they fall in love and they planned their future together [although 3 weeks was pretty fast] she was already 30, people can't get younger, she started to panic, she loved kids and wanted one so she confined to her friend [which is the brother] and he also wanted children, they had a mutual agreement and she became pregnant with his sperm. When they meet, they were at his[the brother's] funeral, they started talking, getting to know each other and then married each other, at their honeymoon she found out she was pregnant. Big emotional happenings may affect the baby so she had to be calm and let her husband cool off too, sure she could've shouted but then they would just argue and it would've turned into a big mess
