If you are experiencing severe pelvic pain during pregnancy, especially if you have placenta previa, it is important to seek medical attention promptly. While waiting for your midwife's response, consider contacting your healthcare provider or going to the nearest emergency room for evaluation. Pelvic pain can be caused by various factors such as round ligament pain or even preterm labor, so it's crucial to get a proper diagnosis and appropriate treatment. Remember to describe your symptoms in detail when seeking help, including the intensity, location, duration of the pain, and any accompanying symptoms like bleeding or contractions. Stay calm but proactive in advocating for your health and the well-being of your baby.
