What Causes Bleeding During Pregnancy
Different factors cause pregnancy bleeding in a woman. Some women may continue to have light periods / smacks during pregnancy, particularly during the first trimester. Following is a sketchy list of a number of likely reasons:
Implantation Bleeding in early pregnancy
If you have come across first trimester bleeding, don’t be panic; some 25% of all women have it in early pregnancy. One primary cause of this bleeding can be implantation.
Why implantation bleeding occurs:
Implantation bleeding consists of pink / brown colored blood, usually lighter than the one observed in menstrual bleeding. It often occurs when the tissue surrounding the egg, adheres to the endometrium and progressively makes its way into the uterine lining.
Doing so, it actually channels into the mother’s blood vessels vis-à-vis eking out blood lakes within it. By the time these blood channels form over the uterus surface they often result in implantation bleeding.
Bleeding owing to miscarriage
Bleeding while pregnant doesn’t always usher in miscarriage, nevertheless there is likelihood. Studies show that nearly half the women who bled did not experience miscarriage.
Miscarriage can trigger at any moment in the first half of pregnancy. Most occurrences are witnessed in the first trimester. About 15 to 20 percent of pregnancies result in miscarriages. If you are certain to have passed fetal tissue, just consult your doctor without delay.
Bleeding can occur in early ectopic pregnancy. If pregnancy happens to hold in a fallopian tube, it is bound to burst / puncture at a later stage. However, the likelihood of Ectopic pregnancies is quite rare compared with miscarriages — about one in 60 pregnancies.
The instances of bleeding in the second half of pregnancy significantly differ from the ones in early pregnancy. Usual agents that inflict minor bleeding may entail a sore cervix or growths over it.
The placenta may detach from the uterine wall before or during labor. This may cause vaginal bleeding. Only 1 percent of pregnant women have experience placental abruption. It usually occurs during the last 12 weeks of pregnancy. Stomach pain often occurs, even if there is no obvious bleeding.
When the placenta lies low in the uterus, it may partly or completely cover the cervix. This is called placenta previa. It may cause vaginal bleeding. Placenta previa is serious and requires prompt care.
Late in pregnancy, vaginal bleeding may be a sign of labor. A plug that covers the opening of the uterus during pregnancy is passed just before or at the start of labor. A small amount of mucus and blood is passed from the cervix. This is called “bloody show.” It is common. It is not a problem if it happens within a few weeks of your due date.
