Nearly falling off 5 times... it's all part of the learning process. You're right, I don't like to say it, but one of these days you will fall off because it happens to everyone, I just hope you don't get anything worse than gravel rash out of it. Being more worried about the bike's health than yours is natural - I crashed in my second race ever and got a heap of gravel rash and got knocked out for 5min, but the first thing I wanted to know when I came to was whether my 2nd hand $250 chromoly bike was ok!

Use these first few months not just to increase your kms and fitness but learn some bike skills too - how to get your water bottle in and out while riding, clipping in and out of clipless pedals (if you have them) and how to corner properly.
