Sam was all smiles as she, Jack, Cameron, Daniel, and Teal'c headed for the last check point on their way to a post Goa'uld extraction celebration lunch. She was already trying to decide between the grilled chicken salad and Caesar chicken wrap when the guard stopped her.

"I'm sorry Colonel, but the infirmary has requested that you not leave base."

"What?"

"We received a call a few minutes ago asking us to stop you and have you return to the infirmary."

"You guys go on to lunch. I'm sure this won't take long and then I'll join you."

Jack shook his head. "Not a chance."

"Well, if he's not going then neither am I, I mean he's the one paying." Cameron grinned.

"Indeed."

With that the whole group followed Sam back to the infirmary where she was invited into Dr. Lam's office alone. "Colonel, thank you for coming back. Did anything unusual happen while you were with the Tok'ra?"

"No, just a few hours of singing before they extracted the Goa'uld. Why?"

"There were some inconsistencies in your test results. I'd like to get another blood sample. It will take us about twenty minutes to rerun the test in question."

"Ok, should I be worried?"

"No, I'm pretty sure it was a false positive, but I'd rather get a new blood sample to confirm it."

"Alright." A nurse came in and took a vial of blood.

Dr. Lam returned fifteen minutes later. "Colonel, could you please come with?"

Sam followed Dr. Lam to a gurney behind a curtain. "Colonel, were you aware that you're pregnant?"

Sam's eyes flew open in shock. "No, there's no way. I mean, no."

"I didn't think so. When you arrived from Atlantis two days ago your blood work didn't indicate you were pregnant, but it does now, and the HCG levels are higher than could happen in a few days."

"What are you saying?"

"I'd like to start with an ultrasound to determine how far along you are."

"Right, ok."

"Please unbuckle your pants and pull your shirt up. The gel will be a little cool." Dr. Lam began moving the wand around and the screen filled with grey blobs.

"Well?"

Dr. Lam removed the wand and wiped the gel off Sam. "I'm moving you to an isolation room."

"An isolation room?"

"I'm sorry but yes, I'll explain everything once you're there."

Dr. Lam rolled Sam past the guys, who were perplexed as she entered isolation room two. All four men moved up to the observation room. Dr. Lam asked two guards to be placed outside the isolation room as she picked up the phone and called General Landry.

She turned off the microphone in the room and came back over to Sam. "Based on the ultrasound you're thirteen to fourteen weeks pregnant. I've double checked your blood sample from when you arrived from Atlantis and it indicates you were not pregnant when you arrived her two days ago. I'll contact Atlantis and confirm you didn't have any positive pregnancy tests prior to leaving, but I seriously doubt if you'd had a positive test they would have neglected to tell you. Based on this I have to suspect this is not a standard human pregnancy."

"So that's why I'm in isolation."

"Correct." Sam sighed as she looked up at the concerned men in the observation room. "Let them know I'm ok."

Dr. Lam nodded. "I'll be back soon."

She went up to the observation room and explained the pregnancy to Sam's team, Jack, and General Landry.

"Do you think this is what Ba'al meant when he warned us?" Daniel glanced over his shoulder at Sam.

Cameron shook his head. "That doesn't make any sense. What would he gain by doing this?"

"I don't know, but until I can establish there wasn't an alien influence in this pregnancy Colonel Carter will remain in isolation." Dr. Lam folder her arms over her chest.

"How do you plan to establish that?"

Dr. Lam looked at Jack. "I am going to do a chorionic villi sample today."

"And if that shows the child is human?"

She shrugged. "I just run the tests."
