Bleeding during pregnancy
Bleeding in the first trimester (weeks one through 12) might occur,
and most women who experience bleeding during pregnancy go on to deliver
healthy babies.
Still, it's important to take vaginal bleeding during pregnancy
seriously. Sometimes vaginal bleeding during pregnancy indicates an impending
miscarriage or a condition that needs prompt treatment. By understanding the
most common causes of vaginal bleeding during pregnancy, you'll know what to
look for — and when to contact your health care provider. Vaginal bleeding
during pregnancy has many causes. Some are serious, and many aren't.
1st trimester
Possible causes of vaginal bleeding during the first trimester
include:
·
Implantation bleeding (which occurs about 10
to 14 days after conception)
·
Miscarriage (the spontaneous loss of
pregnancy before the 20th week)
·
Molar pregnancy (a rare occurrence in which
an abnormal mass — instead of a baby — forms inside the uterus after
fertilization)
·
Problems with the cervix, such as a cervical infection, inflamed
cervix or growths on the cervix
2nd or 3rd
trimester
Possible causes of vaginal bleeding during the second or third
trimester include:
·
Incompetent cervix (a premature opening of
the cervix, which can lead to preterm birth)
·
Miscarriage (before the 20th week) or
intrauterine fetal death
·
Preterm labor (which might result in light
bleeding — especially when accompanied by contractions, dull backache or pelvic
pressure)
·
Problems with the cervix, such as a cervical infection, inflamed
cervix or growths on the cervix
·
Uterine rupture, a rare but life-threatening occurrence in which
the uterus tears open along the scar line from a prior C-section
Normal vaginal
bleeding near the end of pregnancy
Light bleeding, often mixed with mucous, near the end of pregnancy
could be a sign that labor is starting. Vaginal discharge that is pink or
bloody is known as the bloody show.
