Treatment with progesterone in the third trimester of pregnancy has been shown to be associated with the development of ICP, and levels of metabolites of progesterone, particularly sulfated progesterone, [12] are higher in patients with ICP than unaffected women, suggesting that progesterone may have a bigger role than estrogen in ICP.

Most commonly, Braxton Hicks contractions are weak and feel like mild cramping that occurs in a localized area in the front abdomen at an infrequent and irregular rhythm (usually every 10-20 minutes), with each contraction lasting up to 2 minutes.
Placental abruption defined as the separation of the placenta from the uterus prior to delivery, is a major cause of third trimester vaginal bleeding and complicates about 1% of pregnancies. [13] [50] Symptomatic presentations are variable: Some women can entirely ignore the symptoms, while others have mild bleeding or abdominal discomfort and ...
Cocaine use during the third trimester has a 10% chance of causing abruption. Though the exact mechanism is not known, cocaine and tobacco cause systemic vasoconstriction, which can severely restrict the placental blood supply (hypoperfusion and ischemia), or otherwise disrupt the vasculature of the placenta, causing tissue necrosis, bleeding ...
During the third trimester of pregnancy, thinning of the lower uterine segment or contractions caused by cervical dilation can increase the amount of stress placed on the placental attachment to the uterine wall. In patients with placenta praevia, these stresses can cause detachment of the placenta from the uterine wall causing haemorrhaging.
HELLP syndrome patients experience general discomfort followed by severe epigastric pain or right upper abdominal quadrant pain, accompanied by nausea, vomiting, backache, anaemia, and hypertension. Some patients may also have a headache and visual issues. These symptoms may also become more severe at night.
Acute fatty liver of pregnancy is a rare life-threatening complication of pregnancy that occurs in the third trimester or the immediate period after delivery. [1] It is thought to be caused by a disordered metabolism of fatty acids by mitochondria in the fetus, caused by long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency. [2]
