My score dropped 2 points last month and I did NOTHING. Technically, if I did nothing, the only change to my credit would be that my average length of credit increased slightly, which is good, but... Try not to pay attention to those tiny fluctuations. They're always updating their algorithms or shuffling people into different groups for one reason or another. 2 points probably had nothing to do with a payment you made. Think of it like a stock: it can bounce around a bit, but as long as it's overall track is up, it's good.
