What is this? Temp rise after drop around af time? No period yet

ttc14

This cycle has been an emotional roller coaster. Ttc #2 for 8 months. Temps started to drop on cd 23 and I was crushed the next day I had a cream pink discharge only when I wiped. Never showed up on my liner. The day after that wore a liner again and only a single rust colored spot. Now my temps are rising again so took a test this morning and maybe I see a shadow of a line? Maybe it’s wishful thinking. Has this happened to anyone?
