"Do you always have to stay in hospital til the pregnancy has 'passed' in the UK does anyone know? In a way i'd rather go home.. "
Last August I had a surgical abortion (D&C) at 11 weeks 4 days. They thought I was just 8 weeks when I first went to see the consultant and asked me to consider a medical abortion as the risks involved were apparently less dangerous.
I took a leaflet for both medical and surgical and asked questions about both.
You will have to stay in hospital until the pregnancy has passed, you could be there for 2/3 hours or 2 days. If you do get a chance to reconsider, I would suggest reconsidering a surgical termination. With a medical termination there is a chance that you may see the fetus, which can be traumatic for some women, obviously there is the chance of heavy bleeding and it can be quite painful.
My surgical abortion took an hour from going in and waking up on the ward, and most of that was because I was too darn lazy to wake up in the recovery room. I was put to sleep (which was the most traumatic part of the whole experience - being scared of needles and all) and then was back in the ward half an hour later. I did not bleed heavily afterwards, it was just like a normal period and I experienced no pain apart from very slight back pain.
I wish you well, you will be okay.
