Stick with them like everyone else has said , ive had clipless pedals about 6 weeks as well now and ive only fell twice , first time was on the first ride when i had unclipped my left foot but the bike wanted to lean to the right and i didnt get the right foot out in time . second time was when i was travelling through a slightly gravely area and i hit some mud that was wet and the bike just stopped in the mud i had my left foot out already but the bike went right again .
Now im becoming more confident in the shoes/pedals as well and not unclipping unless i really have to whereas when i first got them i would unclip as i aproached any junction so in time im sure you will get used to them and become more confident .
