So confused. Is this a period? 10DPO today. Had this for a few days now!

Since 5DPO I had the slightest bit of light pink spots in my knickers & as the days have gone on it’s got browner. Yesterday was the first day I experienced proper cramps but they weren’t extreme.

Today it’s still brown but slightly darker. Do I log this as a period or not? It just doesn’t seem to be stopping? Anyone had this?? One app says AF isnt due until Saturday & the other says it’s due on Thursday. I normally come on around the 28th. 10DPO today?
