Brown spotting CD 14

Im so confused right now. I woke up this morning with very light dark brown spotting and im only on CD 14. My cycles are usually 32 days long but my last cycle lasted 35 days. Ive never spotted this early and ive never had 2 AFs (if this is the start of that) this close together. Im 32 yo and Ive had blood tests to check for hormonal imbalances and it all came back perfect. I've added a screenshot of my Fertility Friend chart just in case it helps.

My husband and I are in our 5th cycle ttc #4 and these unpredictable cycles have me so bummed out.
