Sorry for your loss. Advice I can give you as a patient who has had the procedure: don't worry, you go off to sleep then wake up none the wiser. Get decent sanitary towels in and expect period like blood loss and cramps for a day or two (maybe more if unlucky). Take pain relief. Now advice as a doctor who has seen hundreds of these operations: they are very safe, very very common (sadly), quick and are handled sensitively and professionally. You will be in good hands, so try to relax. As a patient again, I felt so much better having my miscarriage "over" with the operation. Stock up on nice things to eat and take it easy on yourself.
