This is called her background risk. This fact sheet talks about the critical periods of development and types of birth defects that can result from exposures at different stages of pregnancy. This information should not take the place of medical care and advice from your health care provider. During these times , the body can be very sensitive to damage caused by medications, alcohol or other harmful exposures. Yes, the risk depends on what body part is developing at the time of exposure.
Pregnancy & Child Birth
Written and peer-reviewed by physicians—but use at your own risk. Read our disclaimer. Pregnancy begins with the fertilization of the ovum and its subsequent implantation into the uterine wall. The duration of pregnancy is counted in weeks of gestation from the first day of the last menstrual period and on average lasts 40 weeks. Presumptive signs of pregnancy include amenorrhea , nausea and vomiting , and breast enlargement and tenderness. Preconception counseling assists in the planning of pregnancy through education and risk assessment to help ensure best possible outcomes. Pregnancy can be confirmed definitively via positive serum or urine hCG tests and detection of the embryo on ultrasound.
Pregnancy is a rollercoaster of shifting hormone levels which can have numerous effects. This graphic looks at six key hormones during pregnancy, their roles in the development of the baby, and other effects. Human chorionic gonadotropin hCG hCG is an important hormone in early pregnancy. The corpus luteum is a temporary structure in the ovaries which produces other key hormones during early pregnancy. Its concentration increases from conception and peaks 8—11 weeks after. For the first few days after conception its levels are too low to detect with pregnancy tests, but after implantation its levels double every 48 hours. Progesterone During the early weeks of pregnancy, the corpus luteum produces progesterone.
Development happens quickly during the prenatal period , which is the time between conception and birth. This period is generally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage. The two-week period after conception is called the germinal stage. Conception occurs when a sperm cell combines with an egg cell to form a zygote. About thirty-six hours after conception, the zygote begins to divide quickly.

HIV can be transmitted from mother to child during pregnancy, childbirth, or during infancy from breastfeeding. There are very effective ways of preventing mother-to-child transmission, especially if HIV is diagnosed before or early in the pregnancy and if the mother receives the proper care and medications throughout pregnancy, childbirth, and afterward.
Pregnancy , also known as gestation , is the time during which one or more offspring develops inside a woman. Pregnancy is divided into three trimesters, each lasting for approximately 3 months. Prenatal care improves pregnancy outcomes. Associated terms for pregnancy are gravid and parous. Gravidus and gravid come from the Latin word meaning "heavy" and a pregnant female is sometimes referred to as a gravida. Similarly, the term parity is used for the number of times that a female carries a pregnancy to a viable stage. A woman who has never been pregnant is referred to as a nulligravida.

ABSTRACT: The goal of prepregnancy care is to reduce the risk of adverse health effects for the woman, fetus, and neonate by working with the woman to optimize health, address modifiable risk factors, and provide education about healthy pregnancy. All those planning to initiate a pregnancy should be counseled, including heterosexual, lesbian, gay, bisexual, transgender, queer, intersex, asexual, and gender nonconforming individuals. Because health status and risk factors can change over time, prepregnancy counseling should occur several times during a woman's reproductive lifespan, increasing her opportunity for education and potentially maximizing her reproductive and pregnancy outcomes. Many chronic medical conditions such as diabetes, hypertension, psychiatric illness, and thyroid disease have implications for pregnancy outcomes and should be optimally managed before pregnancy.
Such cares are of nutritional, behavioral and lifestyle natures, and also involve the father and the whole family. Human development, from conception to maturity, consists of a critical and important period due to the multitude of intrinsic genetic and environmental factors that influence, positively or negatively, the person's entire life. The fragility of development continues throughout the preschool, school and adolescent periods during which proper nutrition with a balanced lifestyle is essential and depends on guidance from the parents, caregivers and teachers. It is important to make the distinction between two terms that overlap in practice, namely, growth and development. Growth refers simply to the increase in body size, both weight and stature, while development represents changes in parameters that may or may not depend on growth, involving a very complex series of factors: genetic, epigenetic, nutritional, environmental and lifestyle, amongst others HURLEY, ; STANNER et al. Development is the sequence of ordered alterations that occurs within the organism as from fertilization of the ovum formed in the ovaries, by sperm produced in the testicles, resulting in the oocyte first diploid cell of the new organism to be formed. The alterations are progressive and irreversible; they occur in a regular sequence with slight variations, and each change leads to an organism that is different from the previous one and unable to return to its original stage.

Таких посланий она получила больше двух десятков. И все был подписаны одинаково: Любовь без воска. Она просила его открыть скрытый смысл этих слов, но Дэвид отказывался и только улыбался: Из нас двоих ты криптограф. Главный криптограф АНБ испробовала все - подмену букв, шифровальные квадраты, даже анаграммы. Она пропустила эти слова через компьютер и поставила перед ним задачу переставить буквы в новую фразу.
Чед! - рявкнул у него за спиной Фонтейн. Директор наверняка обратил внимание на выражение глаз Мидж, когда она выходила. - Не выпускай ее из приемной. Бринкерхофф кивнул и двинулся следом за Мидж. Фонтейн вздохнул и обхватил голову руками. Взгляд его черных глаз стал тяжелым и неподвижным. Возвращение домой оказалось долгим и слишком утомительным.
Дэвид говорит по-испански, он умен, ему можно доверять, к тому же я подумал, что оказываю ему услугу. - Услугу? - бурно отреагировала Сьюзан. - Послать его в Испанию значит оказать услугу.
