Really short period

Flossy • 35, married. UK. Mama to Little P 👼🏼💕

My periods seem to be getting shorter. I’ve been off pill since April last year and have been tracking well, but in the last few months my period gone from 4 days to 2. I mean I’m not complaining, but is it something to worry about? I don’t want to google too much and think the worst!
