Anyone experience this?

Fe

According to glow, I ovulated on Aug 20th. Since the 21st, which I always log, I’ve had nothing but breast pain and tenderness. My period Is suppose to come in 5 days. I tested early, like way too early, and got a negative. Anyone else experience this up until their period and not be pregnant? Or did you experience this and found out you were? My partner and I are preventing at this time.
