Months went by, from the warmest of summers to cool autumn nights, and then the frost filled winter months. Lyra and Charlie had spent months trying to conceive their longed for child, but to no avail. Both became adept at sidestepping the questions from Molly Weasley over when they would give her a grandchild, both pretended it wasn't the right time, they weren't ready, they wanted a few more years together first.
But as the months went on and nothing happened, each denial became harder to force out, harder to pretend that they didn't want a child.
But then it happened.
Lyra met Charlie in Romania, so they could spend their few days together as they did each week before she returned to her Auror duties in London. The minute she emerged in the square where they met each week, the minute she was in Charlie's arms again, he knew something was different.
There was a mystery about her, a knowing look in her eye. Charlie all but dragged her to their cabin, where she immediately said the words that filled his heart to overflowing with love.
"I think I might be pregnant."
He hugged her with delight, pressed his hand against her stomach as if to find the baby that was theirs. The baby that he had put there.
"Have you taken the potion yet?" He belatedly thought to ask, three minutes after filling his life with his baby. Lyra shook her head, and suddenly the baby in the room was gone.
"I wanted to wait.. Wanted you to be there." Charlie beamed at her, and pulled her to him again.
"I love you Ly" he whispered.
Hours later, once their reunion had been cemented in its usual way, they prepared to test whether or not a child that was Charlie's and Lyra's resided in Lyra's womb. A small potion bubbled on the stove, a lavendar sprig rested on the table. Charlie brought the now boiled potion over to his wife, and sat down beside her, clinging onto her hand as he prepared for the news that would change his life or break his heart. Lyra smiled at him, squeezed his hand, and lifted the lavendar to her mouth. She placed it gently onto her tongue, and together they counted thirty seconds.
Once the time was up, she removed it, and dropped it into the bowl in front of her. Agonising seconds passed, as they watched the dark blue potion with increasing dread. They expected it to turn clear, a sign that Lyra's womb was empty.
But it didn't.
Suddenly, it changed colour to a stunning, sunny yellow. Lyra's sparkling eyes met Charlie's, only for her to laugh incredulously when she saw that his eyes, too, were filled with tears. They stared at each other, both fixing the moment in their memories, before they moved.
Years later, neither Charlie nor Lyra could remember who moved first. But all of a sudden, they were in each other's arms, hugging, kissing, while a small pot of innocent yellow potion sat beside them.
They stayed that way for several hours, barely able to tear themselves away from each other in their utter delight. For Lyra was pregnant, and they were to be parents.
