Mood-congruent delusion: Any delusion with content consistent with either a depressive or manic state, e.g., a depressed person believes that news anchors on television highly disapprove of them, or a person in a manic state might believe they are a powerful deity. Mood-neutral delusion: A delusion that does not relate to the patients emotional state; for example, a belief that an extra limb is growing out of the back of ones head is neutral to either depression or mania. Themes
In addition to these categories, delusions often manifest according to a consistent theme. Although delusions can have any theme, certain themes are more common. Some of the more common delusion themes are:

Delusion of control: False belief that another person, group of people, or external force controls ones general thoughts, feelings, impulses, or behaviors. Cotard delusion: False belief that one does not exist or that one has died. Some cases also include the belief that one is immortal or that one has lost their internal organs, blood, or other body parts. Delusional jealousy: False belief that a spouse or lover is having an affair, with no proof to back up the claim. Delusion of guilt or sin (or delusion of self-accusation): Ungrounded feeling of remorse or guilt of delusional intensity. Delusion of mind being read: False belief that other people can know ones thoughts. Delusion of thought insertion: Belief that another thinks through the mind of the person. Delusion of reference: False belief that insignificant remarks, events, or objects in ones environment have personal meaning or significance.
They do, however, list several circumstances when a woman should contact her healthcare provider before continuing with an exercise program: vaginal bleeding, dyspnea before exertion, dizziness, headache, chest pain, muscle weakness, preterm labor, decreased fetal movement, amniotic fluid leakage, and calf pain or swelling (to rule out thrombophlebitis). Sleep
It has been suggested that shift work and exposure to bright light at night should be avoided at least during the last trimester of pregnancy to decrease the risk of psychological and behavioral problems in the newborn. Dental care
The increased levels of progesterone and estrogen during pregnancy make gingivitis more likely; the gums become edematous, red in colour, and tend to bleed. Also a pyogenic granuloma or "pregnancy tumor", is commonly seen on the labial surface of the papilla. Lesions can be treated by local debridement or deep incision depending on their size, and by following adequate oral hygiene measures. There have been suggestions that severe periodontitis may increase the risk of having preterm birth and low birth weight; however, a Cochrane review found insufficient evidence to determine if periodontitis can develop adverse birth outcomes. Flying
In low risk pregnancies, most health care providers approve flying until about 36 weeks of gestational age. Most airlines allow pregnant women to fly short distances at less than 36 weeks, and long distances at less than 32 weeks. Many airlines require a doctors note that approves flying, especially at over 28 weeks.
