Yes, a heartbeat of 183 beats per minute is considered normal at 7 weeks of pregnancy. During early pregnancy, the fetal heart rate can vary between 100 and 180 beats per minute, with higher rates being more common in the earlier stages. As the pregnancy progresses, the heart rate will gradually decrease and stabilize within a normal range. It's important to note that individual variations are possible, so if you have any concerns or questions about your specific situation, it's best to consult with your healthcare provider who can provide personalized guidance based on your medical history and current condition.
