No period in 50-60 days

Been taking the pill off and on for a few years. Never missed a period on the pill. Went off of it almost two months ago (the days all blend together lately) and got my bleeding right away, but no period since. Thought I was feeling some pms but that was a week or so ago and I’ve still not gotten my period. Is this normal or should I be concerned? Literally zero chance of pregnancy (haven’t had sex ever, haven’t had sexual contact with a man in a year or so) so I’m concerned about other reproductive problems. Thoughts?
