Which symptom might indicate a problem with placental attachment during pregnancy?

Severe abdominal pain can indicate a problem with placental attachment during pregnancy, such as placental abruption or placenta previa. When the placenta detaches from the uterine wall prematurely (placental abruption), it can cause significant pain and may lead to serious complications for both mother and baby. Similarly, with placenta previa, where the placenta covers the cervix, there can be lower abdominal discomfort, particularly if there is bleeding and pressure.

In the context of pregnancy, the other symptoms presented—frequent headaches, mild backache, and normal swelling in feet—are generally not indicative of placental issues. Frequent headaches may arise from hormonal changes or stress, while mild backaches are common due to the physical changes occurring during pregnancy. Normal swelling in the feet is often a typical response to the increased fluid volume and weight bearing during gestation. However, if swelling becomes severe or is accompanied by other symptoms like sudden weight gain or elevated blood pressure, it may warrant further investigation.
