Late or not yet ?

Christiana

So I’m almost 5 months pp my period has been a little irregular since I’ve gotten it back , so far it’s been way early like comes every 2-3 weeks instead of every 30 days and so far this month it didn’t come on the predicted early day but since it’s been coming early and has not come yet is it considered late ? Like should I be worried and running out to get a pregnancy test ?
