I am currently 21 weeks, and just had me scan. My OS is completely covered, and have an appt with a consultant next week to discuss. What I really wanted to know was how was it for any of you who had this? And also my midwife told me to pack an emergency bag to have with me in case I need to go in - what items really helped you to pack? This is my second child, and I between 30 and 40 minutes from the hospital. Tia x
