That week was the longest of their lives.

Derek and Stiles had decided that it would be best to keep this on the down low just in case it was a false alarm. Derek saw how careful Stiles was as he went through his daily life. Doing his best to avoided stress and physical exertion. It was obvious that the minute Stiles had left Derek's house he had gone back to his own and done as much research as he could before he needed to go back to carrying on with life.

After they finally pulled away from each other that day, the couple took a shower and changed before sitting down to seriously talk about what their next move would be. The word "if" was thrown around a lot that day.

"Stiles it is amazing that you are willing to go through this so that I can have a family but I honestly don't know what it entails and if at all it runs the risk of losing you I can't go through with it," Derek looked at his mate from across the table. They were sitting having breakfast, Peter still wasn't back yet so they had the house to themselves.

"So that we can have a family. If there is a chance I might be pregnant then I will look into every aspect of it and I can work with Deaton to ensure the safest possible game plan for me and the baby." Stiles gave off the scent of certainty and longing and love. Derek knew that it would not be easy to persuade him away from having this baby even if his own life was in danger.

"I want to know everything, don't hide anything because you think you're protecting me or whatever else you convince yourself you're doing for my benefit. I want to be there as often as I possibly can when you talk to Deaton and do research."

"I'm fine with that," Stiles smiled and took a big bite of his eggs.

They chatted easily for the rest of that morning and when Peter finally decided to rear his ugly mug Stiles decided that it was his time to leave. Derek walked him to his jeep and stood and watched as the human drove away. Everything was happening so fast. Yesterday he was in heat trying to deny his wolf of its mate; today he was perfectly normal and there was even a possibility that he might be a dad.

Seven whole days had passed and finally Stiles had snapped. When Derek slid into his window that afternoon he was met with a fuming Stiles standing pointedly with his arms crossed over his chest staring at him as if he had just run away with 3 blondes and Stiles had caught him in the act. Derek set his feet on the floor with measured ease, he moved toward Stiles slowly trying not to make abrupt or startling movements.

"Derek it has been seven whole days! The week from Hell is over, we are going to see Deaton, now!" Stiles screamed in a whisper then stared at Derek expectantly.

Derek opened his mouth hoping words would just fall out, any words at that point would be great. When nothing came to him he just nodded. Stiles nodded back almost defiantly and grabbed his satchel filling it with research he had printed out that he wanted to discuss with Deaton and different lore books he had either ordered online or got at the library.

Derek just stood watching him, he was aware of the Sheriff's presence downstairs and was glad that Stiles didn't actually yell at him. The alpha finally found some words and said, "I'll meet you in the car," without waiting for Stiles response he slipped back out the window and slid back into the camaro that he had just gotten out of. The engine hadn't even cooled yet.

Stiles emerged from the house three minutes later finishing up a sentence as he shut the door and moved toward the car. When he got in he said, "I told my dad that I was going over Scott's house for the night," Derek nodded, "I'm going to take my jeep and meet you there. He doesn't know that you're here and obviously knows that I'm not walking to Scott's. I'll meet you at Deaton's, okay?"

"Okay," Derek grabbed Stiles hand before the boy slid out of the car and pulled him in for a kiss. Then he placed his forehead to the human's and said, "no matter what happens I'll be right there and we will work through it together."

Stiles smiled and closed his eyes. He kissed Derek again as he pulled away, "of course."

Stiles pulled into the vet right after Derek. The wolf got out of his car and met Stiles at his jeep just as he opened the door. Stiles could see the anxiety plain as day on his mate's face. He raised his hand and used his thumb to smooth the skin between Derek's eyebrows.

"We'll be fine, not matter what."

With that they turned toward the vet. Stiles called out for Deaton once they were both inside. He knew that he could cross the gate but didn't want to intrude and didn't know what it would do to the maybe baby that he might be carrying. His research had given him conflicting views; some saying that the baby would be unharmed, others saying that the barrier could cause a miscarriage and different birth defects. Deaton made his way to the front of the building, looking at them questioningly before his eyes fell on their interlocked hands, something seemed to click for him and he opened the gate and motioned them to come through and follow him to the back.

"I see you two have mated," said Deaton as he tidied up the already clean area. He then turned toward the couple and asked, "what brings you here today?"

The couple exchanged an embarrassed look. They knew they would have to tell Deaton they just didn't want to say it all out loud. Deaton stared at them waiting for one of them to speak.

Finally Derek spoke up, "Well the last full moon I went into heat and had chosen Stiles to be my mate and to mate with…" he told the story only paling slightly at having to explain his sex life to Deaton. Derek obvious left out the more specific details but even the bare bones of the story was enough to make him blush.

Deaton sighed and left the room. He came back with an ultrasound machine. Derek hadn't seen one of those since his mother was pregnant with his little sister Cora. The wave of nostalgia that hit him was enough to worry him even more. He became jittery as Deaton plugged in the machine and Stiles changed into the gown that Deaton had handed him.

Stiles swallowed his anxiety as he removed his shirt and jeans and replaced them with the surgical hopped up onto the examination table and situated a blue blanket over his lap. He only knew what an ultrasound machine looked like because of the amount of times he's been in the hospital with possible internal bleeding but this time was totally different. He was giddy as he slid up onto the table. Stiles took ahold of his mates hand and smiled up at him only to be met with a face of worry.

"It will be alright Derek, I can feel it in my bones."

"You and your boney instincts is what got you kidnapped by that coven of witches," Derek retorted.

Stiles did his best to only look mildly offended, how was he suppose to know those bitches had bugged the cave that Stiles said they should use as HQ. "Whatever, this is different."

The younger man settled back as the vet re-entered the room. They held hands as Deaton wheeled over a stole and flicked on the machine. It whirred to life. Deaton secured the blanket around Stiles' waist before pulling up the gown to expose his belly.

"Now Stiles this gel is going to be a little cold," said Deaton as he poured a very cold blue gel onto Stiles' stomach, the boy hissed slightly and reflexively squeezed Derek's hand. "Sorry", muttered the vet before he grabbed the wand from where it hung from a hook on the side of the machine. He used it to spread the gel around before he went searching for any anomalies.

After what felt like forever in silence Deaton had stopped the wand and looked at the screen. He pointed to a small white blob that was not bigger than a peanut. "There that is your baby, it looks like s make shit uterus has been constructed around it and has attached its the front of your intestines which is where it would be if you were female-" Deaton kept talking but Stiles and Derek heard none of it.

Stiles was pregnant. They were going to have a baby.
