Period Came Early?

Got a question for you guys. I started spotting yesterday out of the blue (I’ve been on Junel Fe for just over a year) but didn’t think much of it. I woke up this morning, and everything was back to normal; however, I came home from work today with period-like cramps and discovered that the spotting is back...and is fresh blood. I’m a week-and-a-half away from my placebo week, and my fiancé and I were getting frisky on Wednesday (no penetration, though). What’s going on?
