During an 8-week ultrasound scan, you can expect the healthcare provider to use a transvaginal probe to visualize your uterus and the developing embryo. They will check for the presence of a heartbeat, measure the size of the embryo, and assess its overall development. It is normal for some women to not experience sore breasts during early pregnancy, as symptoms can vary from person to person. However, it's always best to discuss any concerns with your healthcare provider who can provide personalized guidance based on your specific situation. Remember that every pregnancy is different, and it's natural to feel worried or anxious after experiencing a previous miscarriage. Open communication with your healthcare provider and seeking emotional support from loved ones can help alleviate some of these concerns.
