After labor it is the contraction of these muscles that physically squeeze the blood vessels so that hemostasis can occur after the delivery of the fetus and the placenta. [1] Local hemostatic factors like tissue factor type-1 plasminogen activator inhibitor and platelets and clotting factors aid in stopping the blood flow.
Braxton Hicks contractions allow the pregnant woman's body to prepare for labor. [1] However, the presence of Braxton Hicks contractions does not mean a woman is in labor or even that labor is about to commence. [1] Another common cause of pain in pregnancy is round ligament pain. Table 1. Braxton Hicks contractions vs. true labor [1]
Uterine contractions are muscle contractions of the uterine smooth muscle that can occur at various intensities in both the non-pregnant and pregnant uterine state. The non-pregnant uterus undergoes small, spontaneous contractions in addition to stronger, coordinated contractions during the menstrual cycle and orgasm.

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 ...
Smooth muscle cell contraction: At ovulation, this pain may be related to smooth muscle cell contraction in the ovary as well as in its ligaments. These contractions occur in response to an increased level of prostaglandin F2-alpha, itself mediated by the surge of luteinizing hormone (LH).
Patients can have pain secondary to uterine contractions, uterine tetany or localized uterine tenderness. Signs can also be due to abruptio placentae including uterine hypertonus, fetal distress, fetal death, and rarely, hypovolemic shock (shock secondary to severe blood loss). The uterus may adopt a bluish/purplish, mottled appearance due to ...
Uterine rupture is when the muscular wall of the uterus tears during pregnancy or childbirth. [3] Symptoms, while classically including increased pain, vaginal bleeding, or a change in contractions, are not always present. [1] [2] Disability or death of the mother or baby may result. [1] [3]
