Hi and thanks for using the forum.
If your only symptom is spotting then you can wait to see what happens with your next period. If you are having other symptoms such as abdominal pain, fever, pain during sex, then you should get checked out by your ob/gyn. It is not uncommon to spot from time to time, but if this persists through your next cycle, then I think you should see your ob/gyn. Also, if your are worried or concerned, there is no harm in calling your ob/gyn and letting them know what is going on. They can let you know if you should come in to be seen or if you can wait this out. I hope this helps. Good luck.
