help with nuvaring

for a couple of months, i had been doing the whole “keep it in for three weeks, take it out for one, repeat the cycle” thing. three weeks ago i decided to just replace the nuvaring and not have a free week. i didn’t get my period up until today (i think it’s my period, we will see) so i got my period about 2-ish weeks late (normal 28-30 day cycle became 45 days). i’m supposed to swap my ring out tomorrow, should i swap it and keep a new one in or just take it out and have a ring free week?

im just not super sure what to do or if this is normal

also as of thursday i am not pregnant at least 😭 went to the ER for a separate issue and that test was negative at least
