One day period

So, a bit worried. I was a few days late for my period and it finally came. However, it only lasted one day. It was pretty light but I did have 2 clots. I'm on the pill and always use condoms when I have sex. My period have always been super short (3 or 4 days) but this is really short for me. Should i be worried or no? I'm just really at a loss of how to interpret it.
