Okay Help

So my last period was really weird and really really light. Never had that happen before. And the last 4 days I’ve had random little cramps on my right and left side and by my right hip and have felt nauseous and my boobs are sore and I’m tired and hungry ALL the time. I had unprotected sex during my ovulation time and me and the said person just broke up a few days ago. I’m approximately 4 days before my next period does it sound like I could possibly be pregnant?
