It will be interesting to see what happens tomorrow on your no bread day. Start your day by taking your waking/fasting BG, then test at least 1 and 2 hours after eating, same for lunch and dinner. if you exercise, take a reading before you start and when you finish. And finally, take a reading when you head to bed. Note down all the readings (time, level and any food taken). After a few days you should start to see how the things you eat and do affect your numbers and you can start to make adjustments, recording the results along the way. I used an Excel spreadsheet in the early days and noted absolutely everything from food and exercise to mood and weather. An point to note is that fat in a meal will likely slow the rise in post meal BGs so you may hit the peak later than you expect, this is one reason for the three tests after eating.
This is a lot of testing, but it's extremely valuable in the early days as you learn how your diabetes works and how to 'manage' it. It's the only way IMO to really get things under control, without testing you're left completely in the dark and a hostage to fortune.
