Update: oops thought my chart was posted...i added it now

My period was due the 25th but nothing. I had spotting started the 21st which was brown all the way to the 23rd. In between it was light pinkish/weird reddish color then it stop then it come back again...i am getting pulling sensation in my breast and when i squeeze lightly sometimes i get clear sticky fluid with streak of white...i am honestly thinking of testing since i spotted them days and no new chart started. An app predicted the 21st would be implantation day but idk abt all that cause my temp is all over even though its not taken on time each day cause i oversleep
