Is Bleeding During Pregnancy Normal?

Bleeding during pregnancy automatically causes a mother-to-be to envision the worst. However, bleeding isn't always an indication of bad things, and it is more common than many women realize. Learning exactly what to look for and connecting the bleeding with other signs and symptoms can give women a chance to know when nothing's wrong and when it's time to visit the doctor.

First Trimester
Bleeding in the first trimester is most common and is often not a cause for concern. Implantation bleeding happens when the egg attaches itself to the tissue-lined uterus. Some of the spongy blood-tinged lining can slough off and exit the vagina.

Miscarriage is another cause of first trimester bleeding and generally will occur within the first 4 to 12 weeks. Sometimes a woman will have a miscarriage and think that it is just her normal period.

Some cervical infections can also cause bleeding. Sometimes the cervix receives more blood flow, and bleeding may occur after intercourse. Cervical cancer is also another more serious cause of first trimester bleeding.

Second And Third Trimester
Normal vaginal bleeding can occur in the later trimesters as well. When a woman is nearly ready to deliver, the thick mucus plug releases from the opening of the cervix. This bloody show means that labor is anywhere from a few days to a week or two away.

Some bleeding during late trimester pregnancy is a warning sign. Bright red blood could mean that the cervix is opening early, signaling preterm labor, especially when a woman has contractions and back pain accompanying it.

Although rare, a uterine rupture could also be a cause of second or third trimester bleeding. If a woman has had a Cesarean section previously, a uterine rupture could occur if there is some tearing along the scar.

When To See The Doctor
Generally, for light spotting or bleeding that passes within a few hours, it's sufficient to make a phone call into the doctor to let her know. If the bleeding is longer than a few hours, is significant in volume or is accompanied by cramps, contractions, fever or pelvic pressure, visit the doctor immediately.
