Should I say something to people who came to my wedding and gave nothing?

I just had my wedding 3 weeks ago and had about 5 couples that gave no wedding gifts. I plan on waiting months before I draw a conclusion but I was wondering prematurely, what if nothing ever comes. Do I confront them? I could care less about the gifts, I just can't get over the laziness and inconsiderate behavior. The wedding was well received by many and it cost $110 a plate. There was also a couple that did not come because they said their kid was sick. We still had to pay for their plates and we had already gone to their wedding last year. I am not extremely close to them. I have low expectations that they will send something, so what do I do?
