Spotting - Curious

Has anyone experienced spotting prior to a period?

I have had spotting for 3 days now. Pink to light red, barely enough to use a panty liner but I do just in case. My period isn’t due until 8-11 depending on which app I rely on. I had some cramping randomly throughout the day two days ago. My breasts have been sore also which could be PMS.

Has anyone had symptoms like this before BFP? I haven’t tested yet since I’m still waiting on my period, but was curious. TIA.
