Help!

This has been happening for about the last 3 months and it’s starting worry me! I have really regular periods, but the last few months I have been having a really light period/spotting starting the day I ovulate, and last about 5 days.

I’m 24, no kids, and I don’t take any sort of birth control, my husband and I aren’t ttc and we just naturally plan things around my cycle. So this makes it a little difficult.
