Breast tenderness is common during the first trimester, and is more common in women who are pregnant at a young age. Melasma, also known as the mask of pregnancy, is a discoloration, most often of the face. It usually begins to fade several months after giving birth. Timeline
The chronology of pregnancy is, unless otherwise specified, generally given as gestational age, where the starting point is the beginning of the womans last menstrual period (LMP), or the corresponding age of the gestation as estimated by a more accurate method if available. This model means that the woman is counted as being "pregnant" two weeks before conception and three weeks before implantation. Sometimes, timing may also use the fertilization age, which is the age of the embryo since conception. Start of gestational age
The American Congress of Obstetricians and Gynecologists recommend the following methods to calculate gestational age:
Directly calculating the days since the beginning of the last menstrual period.
In the United States, some actions that result in miscarriage or stillbirth, such as beating a pregnant woman, are considered crimes. One law that does so is the federal Unborn Victims of Violence Act. In 2014, the American state of Tennessee passed a law which allows prosecutors to charge a woman with criminal assault if she uses illegal drugs during her pregnancy and her fetus or newborn is harmed as a result.However, protections are not universal. In Singapore, the Employment of Foreign Manpower Act forbids current and former work permit holders from becoming pregnant or giving birth in Singapore without prior permission. Violation of the Act is punishable by a fine of up to S$10,000 (US$7300) and deportation, and until 2010, their employers would lose their $5,000 security bond. Teenage pregnancy
Teenage pregnancy is also known as adolescent pregnancy. The WHO defines adolescence as the period between the ages of 10 and 19 years. Adolescents face  higher health risks than women who give birth at age 20 to 24 and their infants are at a higher risk for preterm birth, low birth weight, and other severe neonatal conditions. Their children continue to face greater challenges, both behavioral and physical, throughout their lives. Teenage pregnancies are also related to social issues, including social stigma, lower educational levels, and poverty.
