If your doctor doesn't order an ultrasound despite your concerns about chronic uterine pain during pregnancy, it is important to advocate for yourself and seek a second opinion. Persistent pain can be a sign of underlying issues that need to be addressed. Contact another healthcare provider or consider consulting with a specialist in maternal-fetal medicine or reproductive endocrinology. Remember, it's crucial to prioritize your health and the well-being of your baby by seeking appropriate medical attention and guidance throughout your pregnancy journey.
