  2. Beginning of pregnancy controversy - Wikipedia

    en.wikipedia.org/wiki/Beginning_of_pregnancy...

    A protein called early pregnancy factor (EPF) is detectable in a woman's blood within 48 hours of ovulation if fertilization has occurred. However, testing for EPF is time-consuming and expensive; most early pregnancy tests detect human chorionic gonadotropin (hCG), a hormone that is not secreted until after implantation. Defining pregnancy as ...

  3. Position (obstetrics) - Wikipedia

    en.wikipedia.org/wiki/Position_(obstetrics)

    In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of childbirth .

  4. Fertility awareness - Wikipedia

    en.wikipedia.org/wiki/Fertility_awareness

    The cervix changes position in response to the same hormones that cause cervical mucus to be produced and to dry up. When a woman is in an infertile phase of her cycle, the cervix will be low in the vaginal canal; it will feel firm to the touch (like the tip of a person's nose); and the os—the opening in the cervix—will be relatively small ...

  5. Cervical pregnancy - Wikipedia

    en.wikipedia.org/wiki/Cervical_pregnancy

    The more advanced the pregnancy, the higher the risk for major bleeding necessitating a hysterectomy. [9] On very rare occasions, a cervical pregnancy results in the birth of a live baby; [10] typically, the pregnancy is in the upper part of the cervical canal and manages to extend into the lower part of the uterine cavity.

  6. Cervical effacement - Wikipedia

    en.wikipedia.org/wiki/Cervical_effacement

    Prior to effacement, the cervix is like a long bottleneck, usually about four centimeters in length. Throughout pregnancy, the cervix is tightly closed and protected by a plug of mucus. Effacement is accompanied by cervical dilation. When the cervix effaces, the mucus plug is loosened and passes out of the vagina.

  7. Human embryonic development - Wikipedia

    en.wikipedia.org/wiki/Human_embryonic_development

    The normal period of gestation (pregnancy) is about nine months or 40 weeks. The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus. The germinal stage takes around 10 days. [1] During this stage, the zygote divides in a process called cleavage.

  8. Cervical dilation - Wikipedia

    en.wikipedia.org/wiki/Cervical_dilation

    In the later stages of pregnancy, the cervix may already have opened up to 1–3 cm (or more in rarer circumstances), but during labor, repeated uterine contractions lead to further widening of the cervix to about 6 centimeters. From that point, pressure from the presenting part (head in vertex births or bottom in breech births), along with ...

  9. Ladin's sign - Wikipedia

    en.wikipedia.org/wiki/Ladin's_sign

    Ladin's sign is a clinical sign of pregnancy in which there is softening in the midline of the uterus anteriorly at the junction of the uterus and cervix. It occurs and is detectable with a manual examination at about 6 weeks' gestation. [1] Ladin's sign is often present during the woman's first pelvic exam when pregnancy is suspected. [2]
