Spotting 7days before period. Do not have cramps or breast pains or pregnancy symptoms. I usually have breast pains before period. What does this mean?

Could be normal. Occasional spotting/ irregular periods can be perfectly normal. Anything that throws off your hormones (antibiotics, stress, travel, diet change, exercise level change) can cause this, and it should return to normal after another cycle or two. If you have any reason to believe you could be pregnant, though, take a test. And get seen if you have discharge with the spotting or foul odor.
