Spotting or period

D. ttc bby #1🦋✨

So now that I’m ttc I’ve been paying a lot of attention to my period. Obviously I’ve been using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>. But I think it’s a possibility that I not logging the correct period dates. My period is normally 3 days . And honestly the next morning nothing. Today I woke up as i would assume my period was over but I wiped it was A lot of blood . Like a normal period. I put in a panty liner and it caught brown blood . But then later I wiped it was pink. Then a little bit ago it was completely gone . Should I mark this is my period or just say it’s spotting. It does change my o date. It’s not a huge deal because I’m using opks but I would like to know .
