She didn't knew what's going on. All she knew is that people started to turn into dust and disappear. She didn't knew who was gone and where they were gone, but she needed to find him first.

Natasha looked for Steve everywhere, she ran into the deep woods trying to find him.
Eventually, she found him on the ground, right next to vision dead body, breathing heavily. Suddenly, she felt nausea 'no not now please not now' she thought to herself.

The truth is, Natasha was 3 weeks pregnant, obviously Steve was the father, and she usually had a lot of morning sickness's. But the feeling right now in her stomach and throat, was different than usual. She couldn't explain it, but the feeling in her body was really burnt her inside.

She put her hand on her stomach and started breathing heavily, trying to swallow the liquid that's going to get out of her mouth.
Steve looked up at her, making sure she was really there. He got up from his legs and hugged her tight, her eyes widened at the surprise. He didn't care that his friends beside Sam and Wanda (that disappeared too) didn't knew about them, all he needed was her. The tightness Steve put her in caused her to pull away and vomit.

"a-a-are you alright Nat?" he asked worried, putting a hand on her back and soothing her
"No" she answered and right after vomited again. Her pregnancy was a secret for now, they needed some time taking it themselves
"do you have morning sickness? Now?" he whispered to her, not wanting anyone to hear
"I don't know" she looked at him with a confused look. Just like him, she didn't knew what's going on.

Time passes and everyone got back to the palace, they are staying there for the night because the quinjet is harmed and it needed to get fixed. While they were staying they took some medical exams, to stitch up their wounds and see if everything is good.

Steve and Natasha were the last to do the exams, taking care of their friends before themselves. Steve got in first although he wanted Natasha to be, but she said that his wounds needed attention, and it's more urgent than her vomiting.

Natasha was anxious, she didn't knew what was going on with her and the baby. When the went to the doctor, he said that her pregnancy might be dangerous, considering the fact she doesn't supposed to have kids since she was sterilized. She was deep in her thoughts that she didn't notice Steve coming into the room. " Nat, ummm, you should go get checked." he told her "yeah..." she said nervously. Before she came out she turned around to look at him
"Steve, if something happens to the baby, will you be mad?" she asked him curiously
"No, of course not Nat. This is not your fault. Baby or not, I still love you." he said and came up to her, and pecked her lips
"okay. Good luck" she said and closed the door.

Steve sat on the bed nervous, thinking what he was going to do when all of his friends are gone. He put his head in his hands and put fingers through his hair. He mostly thought about Natasha and the baby. He knew how happy she was when she first found out she was pregnant, he didn't want her to be sad if something will happen.

Natasha got in to the room, shaking and breathing heavily. She stood by the door for a moment and then talked "I lost it." she said and her voice broke. She was so sad, it might was her only chance to have a real family, and Thanos took that away from her too. "oh Nat" Steve said pitiful "come here baby" he lifted his hands hinting her to come in his hug, she straddled his lap, wrraped her hand around his neck and put her head on his shoulder. She let out a shaky breath, almost crying. She didn't like to cry next to him, but every time they were like that, he knew the crying will come at some point. "you can cry Nat." he whispered in her ear, she took another breath and started sobbing, and the crying.

"how could I be upset about something I never had?" she asked with a broken voice.
He didn't answered, he didn't knew what to say in a situation like this, but it was hard for him as well, thinking he could finally have what he wished for, a wife and kid " I don't know what I'm supposed to say in here, but I need you to know that even if we won't ever have a baby, I don't care. And long as I have you." he tried to soothe her "I know, you're right." she said and sniffed. "you want to take a bath?" he asked and pulled away from their hug to look at her "yeah" she mumbled and wiped her tears "please don't cry." he said and cupped her cheeks and wiped her tears. She laughed at the gesture.

He lifted her up, her legs wrapped around his waist and her arms around his neck and her head buried in the crook of his neck, sniffing his scent. He carried her to the bathroom and put her on the counter while he prepared the bath, when he was done, he took off her clothes and then his, and getting in the bath together. She sat in his lap and put her head on his chest, and he wrraped his arms around her belly. He massaged her shoulders, neck and back to help her relax a little bit.

When Steve started to feel the water getting a little cold, he got out of the shower and brought shower robes for both of them, pulled Natasha out of the shower and let her put on her robe. They sat and talked on the bed for a few minutes, comforting each other. Steve leaned in to kiss her softly and she kissed him back. Soon the kiss became heated and started their few hours makeout session, forgetting about the world and their problems, focusing on themselves.

When the time was almost 3AM, Steve and Natasha were both tangled naked in their sheets, caressing each others face and falling deep in their eyes.
" it's gonna be okay Nat" he said and caressed her hair "I know. I just hope they'll get back." she said, he could hear the exhaustion in her voice "they will. Thanos is still out there, we'll find him and bring everybody back." he said and kissed her forehead "alrgiht. I trust you." she said and smiled at him, he smiled back at her "I love you." he said softly "I love you too." she responded with a yawn "okay let's get some sleep" he told her, turning her around to spoon her.
"goodnight baby" Steve said
"goodnight soldier" she smirked and right after, fell asleep in his arms.
