Bleeding which occurs before 24 weeks is known as early pregnancy bleeding. Causes of bleeding before and during childbirth include cervicitis, placenta previa, placental abruption and uterine rupture.
Before 10 weeks gestation, a slower than normal increase in hCG suggests early pregnancy loss or ectopic pregnancy. [19] By approximately 10 weeks, hCG plateaus and ultrasound is preferred to determine the location of the pregnancy (i.e., intrauterine or ectopic). [19] In the presence of prior pelvic imaging, fetal heart tracing with Doppler ...
Symptoms include vaginal bleeding, abdominal pain, premature labor and threatened miscarriage. [6] Ultrasonography is the preferred method of diagnosis. [7] A chorionic hematoma appears on ultrasound as a hypoechoic crescent adjacent to the gestational sac. The hematoma is considered small if it is under 20% of the size of the sac and large if ...
The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]
Hormone levels, bleeding, a positive pregnancy test and an ultrasound of an empty uterus all indicate an ectopic pregnancy. “You can't be 100% — that's the tricky part," said Kate Arnold, an ...
The presence of a "T-sign" at the inter-twin membrane-placental junction is indicative of monochorionic-diamniotic twins (that is, the junction between the inter-twin membrane and the external rim forms a right angle), whereas dichorionic twins present with a "lambda (λ) sign" (that is, the chorion forms a wedge-shaped protrusion into the ...
Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...
