Can you help? Spotting query.

Hi all, we are trying to conceive after 2 miscarriages. Trying my best to not be obsessive but I’m on day 22 today. Last month ovulated on day 21. Yesterday I had some odd pink/brown spotting. Then again today only when wiping. What could this be. Cycle average is 30 days. Praying I ovulated early and maybe pregnant but doubtful xx
