Before pregnancy has been achieved.
When the umbilical cord slips through the cervix or into the vaginal canal. The cord may actually stick out from the vagina, or the mother may just feel that there is something there. The mother should get on her hands and knees to relieve pressure on the cord and seek urgent medical assistance.
The lower portion of the trunk of the body, bounded anteriorly and laterally by the two hipbones and posteriorly by the sacrum and coccyx.
Of or pertaining to the time during labor and birth, and immediately following delivery.
An Obstetrician who has received further education in the area of high-risk pregnancies and complications.
The area between the vagina and the anus. The perineum is stretched during a vaginal delivery, and may be cut during labour in a procedure known as an episiotomy.
Pica during pregnancy is a condition in which a woman craves and consumes substances with no nutritional value. Affected women have cravings for non-food items such as ice, baking soda/powder, laundry starch, clay, dirt, chalk and ashes. If you find you have such unusual cravings, tell your doctor immediately and request a test for anemia.
The special tissue that joins the mother to her fetus. The placenta provides the fetus with oxygen, water, and nutrients (food) from the mother's blood and secretes the hormones necessary for successful pregnancy. Carbon dioxide and other wastes are passed back through the placenta. These will be processed and excreted by the mother. Shortly after the birth of the baby, the placenta also needs to be delivered.
Implantation of the placenta over or near the internal opening of the cervix.
The premature separation of a normally implanted placenta from the uterus. Symptoms of placental abruption include bleeding, cramping, and abdominal/uterine tenderness.
A posterior presentation occurs when a baby faces toward the mother's front instead of toward her back. Labors with a baby in a posterior presentation tend to be more difficult than usual, because the baby's head does not fit as well into the mother's pelvis nor does it properly fit against the cervix. The baby also has to rotate farther to get into the position for birth. The hard bone in the back of the baby's head presses into the mother's back, which may cause intense back pain ('back labor').
High blood pressure during pregnancy is part of a complicated condition that may arise rather suddenly in the latter half of pregnancy. The condition may also include protein in the urine and/or swelling of the face, hands and feet.
A very quick labor and delivery, which lasts less than three hours from beginning to end.
A blood or urine test that determines the level of the human chorionic gonadotropin (hCG) hormone. Elevated levels of this hormone are chemical evidence of a pregnancy.
Pregnancy documented by a blood or urine test that shows a rise in the level of the human chorionic gonadotropin (hCG) hormone.
Pregnancy documented by the presence of a gestational sac on ultrasound.
Premature rupture of membranes
Frequently abbreviated as PROM, this means that the membranes (amniotic sac) has broken or developed a hole at any time during pregnancy and more than 12 hours before the onset of labor. Preterm PROM occurs when the membranes rupture before 36 weeks of pregnancy.
The part of the fetus that enters the birth canal first. Some presentations include variations of cephalic (head), breech (bottom, legs or feet) or shoulder.
Premature or pre-term labor is defined as labor occurring after 20 weeks and before 37 completed weeks of pregnancy.
First-time pregnancy. (Latin term)
One of the female sex hormones, which is produced by the ovary and placenta. Progesterone prepares the lining of the uterus, for implantation of a fertilised egg, and helps maintain the pregnancy. Low levels of progesterone may increase the risk of miscarriage.
A labour lasting lasting more than 20 hours. There are many reasons why labor may not progress more quickly, and this does not always signify a problem.
A large, complex molecule composed of amino acids.
Protein in the urine, this is often considered a warning sign of pre-clampsia. Protein found in the urine very early in pregnancy increases the risk of such adverse outcomes as giving birth prematurely, having a child who is small for gestational age, or having an infant who would need specialist medical attention after birth.
