Hi there 4getmenot. I was pregnant at the end of October last year. Due to previous miscarriage and ectopic pregnancy I was sent to EPU right away for a scan. They couldn't see anything in the womb, but said that could be quite normal for very early stage of pregnancy. To confirm the pregnancy was continuing normally, I had to have blood tests every 48 hours to monitor the HCG levels followed by another scan a week later. Unfortunately on that occassion the HCG levels didn't rise and after the second scan, I statred to bleed and subsequently miscarried. This took place at 7 weeks according to my dates. Different parts of the country have different practices for this. Please tell your friend not to worry, although from experience I know that is easier said than done! She has to do exactly what the hospital advises. I hope everything goes well for her.
