A/N: This is a prequel to my other story "Frost Bite". It's not really necessary for you to read it first, but if you want to take a look, you can either read this one and then the other one; or whatever you think its best.

Sarah Walker was on the process of freaking out big. She knew a lot of things about a lot of things; but even then she'd missed all the tell-tale signs of her body. She'd always thought it was impossible for a woman to not know she was pregnant. She'd always figured she'd know as soon as the egg nestled in her womb. Well, she was really wrong.

It began with nausea right before she went to sleep. Slightly, just I-ate-something-and-it-didn't-settle-down-well type of nausea. She drank a lot of water; it helped and she forgot all about it. She still got her period that month, the flow was a bit lighter than normal but that never worried her because she had took her contraceptive shot a month before and the doctor had warned her sometimes a little light bleeding could happen until her body adjusted to the new method.

The next month, she never got her period and took notice that her breasts seemed a little tender and swollen; nipples darker than usual. She never thought for a second that she could be pregnant; she just crossed them off as collateral effects from the shot.

"Chuck, are my boobs bigger?"

She had asked that day, coming out of the bathroom wet and naked, hands fondling the tender breasts lightly as if to test the weight. Chuck's eyes bulged and he never answered the question, even if on the process of sucking and fondling her nipples a couple of minutes later he did find them a bit different.

But by the middle of her third month, she saw the light. She was sitting with Ellie on the couch on a girl's only Sunday afternoon, just talking and eating pizza; Ellie painting her toes. Sarah reached for a slice of the pizza, took a bite and suddenly the most delicious taste exploded on her mouth. She wolfed down that slice and four more before realizing Ellie was looking at her with a delighted expression on her face.

"Wut?" She mumbled, already reaching for the last slice on the box.

"Sarah, you ate my half of the pizza." Ellie grinned knowingly at her.

Like a cartoon, Sarah's eyes widened comically and she looked down at the offending, olive filled, half-eaten slice of pizza on her hand. Like one of Chuck's Intersect flashes, Sarah's brain suddenly gathered all the symptoms and with a frown she threw the slice back on the box, shivering madly.

"Oh, no! Oh, no! Oh, no!" Hyperventilating, she barely noticed when Ellie lost the stupid grin and forced her head between her knees, alarmed.

"Sarah, don't pass out, c'mon."

"I'm going to kill your brother! He impregnated me!"

Ellie bit back a chuckle.

"I thought you took the contraceptive shot a couple of months ago."

"I did. Oh my God..." She raised her head, eyes swimming. "Ellie, I can't be pregnant. I don't know anything about being a mom."

Ellie took a long time calming the hormonal mom-to-be and drove both of them to the hospital to draw Sarah's blood and get the confirmation they needed. She couldn't help but be giddy at the prospect of a baby.

"Stupid Chuck with his stupid "I forgot the condom, honey"... I'm going to kill him. I was fine enough with the condoms, but noooo, I had to take a damn contraceptive shot because you idiot brother forgets them more often than not. And HOW was I supposed to know that the damn thing didn't work right away at the first place? It's NOT my fault your brother wanted a QUICKIE on the way home from the clinic. A really nice quickie, it's true, but it got me PREGNANT!"

It was TMI for Ellie, so she made quick work of drawing the blood and tried to tune out Sarah's ramblings. The woman paced the room like a caged lion, waiting for the results. When they came, all the blood rushed out of Sarah's face and Ellie had to push her head between her legs again. Not that she was surprised but to read the POSITIVE in such big, bold letters had taken her off balance once more.

Ellie looked at the results and frowned.

"Sarah, honey. Don't pass out again, ok?" The blond sent her a fearful look. "I think you may be a little farther along then we think. I'm gonna try to have an OBGYN take a look at you right now, ok?"

"Farther along? What do you mean?" She squeaked, jumping to her feet.

"The hormonal level is higher then expected at the beginning of the gestation period. I think you're probably on your way to your 4th month by now."

It was the last thing she heard before the floor rushed to meet her.
