Suspicious period

AF came thursday. She was medium all day n night. Friday she was fairly light. By friday night she completely stopped. Saturday was nothing...not one spot. Sunday afternoon, she peeked out while i peed. Then nothing. Gone. Out of sight. I also do have a random rash acne like thing under my chin....like why lol no itchy.

When should i test to rule out this weird period??

I normally have 3 predictable days. Med light and spotty...this was off.
