132 before dinner is a little high, there could potentially be an issue there. Unless you had ate something high in sugar/carbohydrate less than two hours before.
69 isn't low enough to be a hypoglycemic blood sugar, you'd be looking more at 45. And your blood sugars aren't going significantly high either (except the reading before dinner, I'd expect that to be lower). They're generally within normal range. 72 a few hours after eating is normal, it's a point where you'd be looking at getting another meal

Everyones blood sugar fluctuates throughout the day, up and down within a certain range, that's natural.
The bruising could be a clue as to what the cause is, there are conditions that can cause more/less bruising than normal.
Have you had the results of your blood tests back yet, or are you waiting to see your doctor? Actually, have you seen your doctor today?
