TTC after 4 months off of Nuvaring

I have stopped using any birth control .. I was on birth control pills from 2006 until 2009 . In 2010 until 2012 I Than went to get use the Depo birth control shots than i began to fearful of unable to not be able to keep my fertility. so now in 2020 now I had stopped taking the NuvaRing back in January of 2020. And i have not have not had a period since March 2020. . I was wondering How long between stopping the birth control ..does it usually take to be able to start and hopefully TTC but also my period has not even started and i am 48 days late . I been tested by blood test and everything came out negative. I am also turned 30 years old in january .
