Hello sir and thank you for posting your query here.. Welcome to HealthcareMagic.. I read your question completely and have understood it well enough. Please note.. 1. The report is absolutely normal 2. 8 weeks is too early is internal OS is open, then it s not a major concern. 3. Repeat scan at 12 weeks and please consult a gynecologist if it remains open even then. 4. As of now, do not worry.. Hope this helps. In case you need further assistance please contact me directly by searching my profile Dr Manjunath Metri. Take care..
