First, thanks to everyone in advance for helping wiht my last question.

Now I was driving today, and after being in traffic for about 30 mins (not my choice) the oil pressure light flashed on, and the right off. It did it one more time before I got to work, but it was after more traffic.

It's a 2004 with 78,000 that got an oil change last week.

Am I just over senestitive about the car?

Better safe than sorry, check it out or have a shop do it.
First make sure your oil level is OK.
The next step would be to remove the oil senderunit and install a gauge to check the pressure. If the pressure checks OK then it's probably a faulty sender unit.
