Pregnancy & intestines in 17 sec.

@SmartDoctor1 =============== Pregnancy is the time during which one or more offspring develops (gestates) inside a woman's uterus (womb). A multiple pregnancy involves more than one offspring, such as with twins. Signs and symptoms of early pregnancy may include missed periods, tender breasts, morning sickness (nausea and vomiting), hunger, implantation bleeding, and frequent urination. Stages of Pregnancy: First, Second and Third Trimester A pregnancy is divided into three stages called trimesters: first trimester, second trimester, and third trimester. A trimester lasts between 12 and 14 weeks, while a full-term pregnancy lasts around 40 weeks from the first day of a woman’s last period. In each trimester, the fetus will meet specific developmental milestones. ------------------------------- Prenatal development (from Latin natalis 'relating to birth') includes the development of the embryo and of the fetus during a viviparous animal's gestation.
