Bleeding during pregnancy
Vaginal bleeding during pregnancy can be scary. It's common, however, and it isn't always a sign of trouble. Most women who experience vaginal
bleeding during pregnancy — particularly during the first trimester.
Still,it's important to take vaginal bleeding during pregnancy seriously. Sometimes vaginal bleeding during pregnancy indicates a miscarriage or a condition that needs prompt treatment.
Cervical changes, including more blood flow to the cervix and softening of the cervix, which may result in harmless vaginal bleeding after sex or a pelvic exam
Molar pregnancy (a rare occurrence in which an abnormal mass — instead of a baby — forms inside the uterus after fertilization)
Second or third trimester
Premature opening of the cervix (cervical insufficiency), which can lead to preterm birth
Preterm labor, which may result in light bleeding — especially when accompanied by regular contractions, dull backache or pelvic pressure
In addition to potentially worrisome causes of bleeding, some vaginal
bleeding near the end of pregnancy is normal. As the cervix begins to
thin out and relax in preparation for labor, the thick plug of mucus
that seals the opening of the cervix is dislodged. When this happens,
you might notice a thick or stringy discharge that may be tinged with
blood. This "bloody show" is a normal sign of impending labor that can
occur up to a week or two before delivery.
