Pregnancy can feel like a journey where control is often an illusion. From the moment a fetus enters the womb, they seem to take charge—dictating everything from when to relieve yourself to the timing of labor. Planning a getaway before the baby arrives? Expect that your little one will make their presence known, perhaps at the least convenient time. And as for your due date? Unless you opt for induction, the baby ultimately decides when they will make their grand entrance.
One important aspect of pregnancy that can be influenced by the fetus’s positioning is placenta previa, a condition where the placenta is located low in the uterus, sometimes covering the cervix. This article explores what placenta previa is, its symptoms, potential complications, and management options.
What is Placenta Previa?
Placenta previa occurs when the placenta attaches too low in the uterus, potentially covering part or all of the cervix. This condition affects approximately 1 in 200 pregnancies, and it comes in four classifications:
- Grade 1: The placenta is low but not covering the cervix.
- Grade 2: Marginal previa, where the placenta is adjacent to the cervix but not blocking it.
- Grade 3: Partial previa, with the placenta covering part of the cervical opening.
- Grade 4: Complete previa, where the placenta entirely obstructs the cervix.
The primary symptoms of placenta previa include sudden, bright red vaginal bleeding in the later stages of pregnancy and contractions. The frequency and severity of bleeding can vary; it might subside only to return later, especially as labor approaches.
Causes of Placenta Previa
The exact cause of placenta previa remains uncertain. However, certain risk factors have been identified, including:
- Previous pregnancies
- Uterine scars from surgeries, such as cesarean sections or fibroid removals
- A history of placenta previa in prior pregnancies
- Multiple gestations
- Maternal age of 35 or older
- Racial background other than Caucasian
- Tobacco or cocaine use
Diagnosis is typically made through ultrasound, either during routine checkups or after bleeding episodes for further evaluation.
Complications Related to Placenta Previa
Placenta previa can lead to serious complications for both the birthing person and the baby. Major concerns include heavy bleeding, which could be life-threatening during labor or shortly after delivery, as well as preterm birth. If significant bleeding occurs, an emergency cesarean section may be required, risking early delivery before the fetus’s organs, like the lungs, are fully developed.
Managing Placenta Previa
In some cases, the placenta may shift to a more favorable position as pregnancy progresses. When it does not, the aim is to carry the pregnancy as close to term as possible, typically delivering via cesarean section. Management strategies may include:
- Reducing activity levels
- Bed rest
- Pelvic rest (avoiding intercourse, tampons, or douching)
- Blood transfusions
- Medications to delay labor
- Steroid injections to aid fetal lung development
In severe cases, tocolytic medications may be administered to prevent premature contractions. Generally, cesarean delivery is the preferred method for those with placenta previa, ideally planned for after the 36th week, though emergency options are available if needed.
Precautions for Those with Placenta Previa
To safeguard your health when diagnosed with placenta previa, consider the following guidelines:
- Avoid vaginal intercourse after 28 weeks of gestation.
- Refrain from using tampons or douches and do not insert anything into the vagina.
- If you experience spotting, use a pad and contact your healthcare provider immediately.
- Steer clear of over-the-counter medications or herbal remedies without consulting your doctor.
- Limit heavy lifting and avoid carrying items over 20 pounds.
- Notify healthcare professionals about your condition before any pelvic exams.
- Always keep your doctor’s contact information handy in case of renewed bleeding.
