A/N: Because I'm not a mean girl, here is a continuation of Late, as requested by some. Written because Grace, being Grace, would Google the hell out of her condition. (Note that the following text wasn't actually Googled and was cooked up purely in my noodle. Dear God, don't listen to any of it if you're pregnant. Unless you find yourself overpowered by your attraction to Rigsby and think he might be the father. Then go nuts.)

Early Behavioral Indicators During the First Trimester
Dr. Ahmed Zheela, John Hopkins University
After confirmation of pregnancy via doctor-administered testing, the subject will experience some if not all of the following behavioral departures from her normal state. Though not unusual, it is imperative for the subject to recognize these changes in her own personality as due to her altered biochemistry. Hormonal increases and unpredictable doses into the bloodstream can have unforeseeable effects. Such changes are as follows:
1) Anxiety and Hyper-Awareness: The subject is now fully aware of her impregnated condition. Such knowledge affects women differently, though all go through various degrees of shock, especially if the pregnancy was unplanned. She will react differently to the smallest things, aware that they now affect more than just her. Dietary habits are usually the first things to be considered and/or altered. The subject often begins to shun caffeine, sugar and high fat foods at the beginning of her pregnancy, knowing they can have an adverse effect on her unborn child. Driving habits have also been noted to change. Some women become overly-cautious, while others simply take more care in following traffic laws. This awareness also modifies physical comportment. Women often carry themselves differently, often unconsciously so. Their hands and arms are drawn more closely towards their stomach. They often pull back at the hips which creates a small defensive posture more easily protected by her hands. Prior research also indicates this posture is a precursor to dropping into the fetal position, instinctively covering the womb, should danger present itself.
2) Sleep Patterns: Sleep is also affected. Anxiety, as listed above, can often be the trigger for sleepless nights for pregnant women, however hormones can cause the opposite effect, making the woman feel exhausted due to the increase in estrogen and the body's constant endeavor to keep the fetus hydrated and fed. All other bodily functions become secondary. It is vital she listen to her body's need for rest.
3) Inter-Personal Interactions: The subject may find herself reacting differently to the people she shares a constant proximity to. It has been noted that family and blood ties often feel stronger to pregnant women, due to the instinct to build and maintain a protective network of helpers and protectors around her during her vulnerable period. Such behavior can also be seen in other pack animals such as lions and wolves (See Dr. John Addler, Science, May 2008). As with these particular animals, the subject may find herself particularly drawn to the father of her child, unconsciously moving in closer contact to him for the reassurance of his protection. The subject may become overtly aware of her mate's movements while in her sight, and may become emotional when he leaves it. This has been particularly noted in couples who share a deep emotional bond, e.g. married couples, and thus both partners have a serious stake in the outcome of the birth. This behavior, however, rarely surfaces in women who became impregnated as a result of a one-night stand or in women who suffer from psychological issues pertaining to trust. Being ingrained with the imperative of survival, both for herself and her child, the subject only exhibits such affection with the fair certainty it will be returned.
