Is a low-lying placenta the same as placenta previa?

Hello, I am currently around 19 weeks pregnant with my third child.
I had two full-term natural deliveries before, but this time I have been informed that I have a low-lying placenta.
I previously had my prenatal check-ups and deliveries at Lixin Hospital in Zhongli, but this time I switched to a private clinic, Hongqi Maternal and Child Hospital.

1.
The doctor informed me about the low-lying placenta.
Is this the same as placenta previa?
2.
I have not stopped having intercourse with my husband; we do it about once a week.
However, after intercourse, my abdomen feels hard like a ball, and it takes a while to return to normal below the navel.
Is this a normal phenomenon?
3.
I am unsure if it is due to the cold weather, not recovering well from my postpartum period, or if the baby is pressing down on my bladder, but I have experienced some urinary leakage.
How can I improve this? Is this considered urinary incontinence?
4.
I am O negative blood type, and I have previously received an injection at seven months gestation.
However, the doctor for this pregnancy said that since I do not plan to have more children, I do not need to receive the injection this time.
Is this acceptable? Will it affect this pregnancy? Although I have had two children before, I have not encountered these situations, so I hope for your professional answers.
Thank you!

Hello: 1.
The position of the placenta generally moves higher as the weeks progress; having a low-lying placenta in the second trimester does not necessarily mean there will be placenta previa at term.
2.
Experiencing contractions at 19 weeks is not normal.
3.
Most cases improve postpartum.
4.
Please discuss with your obstetrician whether it is possible to receive another injection.

More Info

Low placenta position and placenta previa are related but not identical conditions. Understanding the nuances between them is crucial for managing pregnancy risks effectively.

1. Low Placenta Position vs. Placenta Previa:
Low placenta position refers to a situation where the placenta is located lower in the uterus than normal, but it does not necessarily cover the cervix. Placenta previa, on the other hand, occurs when the placenta is positioned so low that it partially or completely covers the cervix. This condition can lead to significant complications, including severe bleeding during pregnancy and delivery, often necessitating a cesarean section.
In your case, being informed that you have a low placenta position at 19 weeks means that while it is a concern, it may not be classified as placenta previa unless it is confirmed that the placenta is covering the cervical opening. Many times, as the pregnancy progresses and the uterus expands, the placenta can move away from the cervix, resolving the issue.

2. Physical Symptoms After Intercourse:
Experiencing a hardening of the abdomen after intercourse is not uncommon, especially in the context of a low-lying placenta. This could be a result of uterine contractions, which can occur after sexual activity. However, if the hardness persists or is accompanied by pain or bleeding, it is essential to consult your healthcare provider. They can assess whether these symptoms are normal or if further evaluation is needed.

3. Urinary Incontinence:
The leakage of urine you are experiencing could be related to several factors, including the position of the baby pressing against your bladder. This is not uncommon in pregnancy, especially as the uterus expands and puts pressure on surrounding organs. However, if this is a new symptom for you, it is worth discussing with your doctor. They may suggest pelvic floor exercises or other strategies to help manage this issue.
4. Rh Factor and Immunoglobulin:
Regarding your Rh-negative blood type, it is standard practice to administer Rh immunoglobulin (RhIg) to Rh-negative mothers during pregnancy, especially if there is a risk of Rh incompatibility with the baby. This is typically given around 28 weeks of gestation and again after delivery if the baby is Rh-positive. If your doctor has advised against administering the injection this time due to your plans not to have more children, it is essential to discuss this thoroughly with them. They will consider your medical history and the specific circumstances of your current pregnancy to ensure that you and your baby are safe.

Conclusion:
In summary, while a low placenta position can be concerning, it does not automatically mean you have placenta previa. Regular monitoring through ultrasounds and consultations with your healthcare provider will help clarify your situation. Pay attention to your body’s signals, and do not hesitate to reach out to your doctor with any new or worsening symptoms. Your health and the health of your baby are paramount, and proactive communication with your healthcare team is key to a successful pregnancy.
