Missed a Pill

I'm on ortho tri cyclen, and I missed tuesday's pill. And tuesday's pill was the first pill of the last row, which has the most hormones in it. I remembered wednesday morning when I was getting ready for school, and I took it as soon as I remembered. I normally take my pill 10pm, but I took it like...Probably 8:30am wednesday morning. This is the first time I have ever missed a pill, and then a couple days later I had some very very light spotting, and its brown. And I also am having cramping. It's not really painful cramping, but it's there. I still have the spotting and cramping today, and i'm just wondering if this is normal when you miss a pill. Thanks!
