Can you still have spotting and not ovulate? PLS READ

My last period was September 23-28th and then around October 20th I had some pinkish clear discharge only when I wipe (no pad or tampon needed) and I had that for about 2 days but not the full day it would only be once throughout the whole 2 days each and only when I wiped so I didn’t really consider that my period but it might’ve been but if so it was really weird bc I’ve never had that happen before. I was supposed to start my period on the 23rd of October according to the app but I still haven’t started and I’ve been getting negative pregnancy tests, this is the most recent one I took 2 days ago and it looks negative to me. (I know we aren’t supposed to post tests in this group but this is just for reference)
