True cervical pregnancies tend to abort; if, however, the pregnancy is located higher in the canal and the placenta finds support in the uterine cavity, it can go past the first trimester. With the placenta being implanted abnormally, extensive vaginal bleeding can be expected at time of delivery and placental removal.
In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

Thus, the presence of an early pregnancy in a retroverted uterus is not considered a problem. [1] On rare occasions the uterus fails to become anteverted, and the pregnancy continues to expand the retroverted uterus within the confines of the pelvis. By about 14 weeks the size of the uterus fills out most of the pelvis, pushing up the cervix.
Retroverted uterus; Other names: Tipped uterus: A transvaginal ultrasound showing a retroverted uterus during pregnancy. The cervix lies posteriorly to the urinary bladder, and the uterus normally extends superiorly from it, but the direction of the body of the fetus reveals that the uterus extends backwards.
Cervical dilation in centimeters; Cervical effacement as a percentage; Cervical consistency by provider assessment/judgement; Cervical position; Fetal station, the position of the top of the fetal head in relation to the pelvic bones, specifically the ischial spines. The Bishop score grades patients who would be most likely to achieve a ...
Obstetrical bleeding is bleeding in pregnancy that occurs before, during, or after childbirth. [4] Bleeding before childbirth is that which occurs after 24 weeks of pregnancy. [4] Bleeding may be vaginal or less commonly into the abdominal cavity. Bleeding which occurs before 24 weeks is known as early pregnancy bleeding.
Rankins says cervical insufficiency happens when there's painless dilation, or opening, of the cervix, typically in the second trimester of pregnancy, or during weeks 13 through 28.
The mother may experience complications such as vaginal or cervical tears, excessive blood loss, infection of the placental membrane, and postpartum infections. [20] Asynclitism can also affect the development of facial structures and nerves during pregnancy, with lifelong consequences for the child.
