Second Trimester Foetal Development

Maternal pregnancy is divided into three stages of growth and development - the first trimester which involves organogenesis via cellular proliferation, differentiation, and morphogenesis; the second trimester which is centred around organ development and functioning as well as foetal expansion and recognisable movement (quickening); and the third trimester during which the foetus undergoes rapid weight gain.

The second trimester encompasses the foetal weeks 12-24, or clinical gestational weeks 14-26, according to the UCSF Medical Centre and is referred to as the "golden period of pregnancy" since many first trimester discomforts such as nausea, fatigue, breast tenderness, and frequent urination are alleviated as the maternal body adapts to the changing gestational physiology - nevertheless increased placental secretions of progesterone, estrogen, and human placental lactogen, as well as increased abdominal pressure can elicit heartburn, constipation, abdominal pain, and leg cramps.
