Yes, that sounds like it's around your ovulation... Could an ovarian cyst have popped, maybe? Though some people just spot when they ovulate.

I would wait and see how it goes; it may be a one-time weirdness, and if you don't feel "off" in any other way, you can probably just make a note to mention it to your gyno at the next usual checkup. (Maybe you could call in and ask them to put the data in your files?)
