I had a maiden fall when I first went clipless, it was proably within the first week or so.

This was after my DH had held the bike while I practiced cliping in and out for a half hour or so before going onto the street. The next day, I ventured to the local school parking lot. This way I could still practice riding, stopping with the whole clip unclip routine. Then when I felt more comfortable I ventured on to the road

Even now I still unclip my right side long a head before stopping. This way I know I will be able to put my foot down without any problems.

Practice, practice and more practice. Soon it will become second nature and you'll love how it makes riding so much more fun.
