Weird period!! Help!

K • Momma of 1 💕

For 2 months in a row my period has came late i have been ttc and last month my period was a 36 day cycle so I thought I was pregnant because my cycle can be anywhere between 26-32 days I’m irregular but on the 36th day my period came! Now this month I’m at 32 days and still no sign I had light spotting 2 days ago now everything is cleared up what could this be?
