That's definitely strange and not how the pill is supposed to work! Personally, I would call your doctor. Before getting covid you had no issues and had the usual 3 weeks of nothing (not even break through spotting) and then the 'off' week of sugar pills, had the traditional BC bleeding (which isn't a period). The pill works to prevent you from ovulating. The issue I'd be concerned with is that someone, you have ovulated and are actually getting a period so the pill is not effective right now. I'd use back up birth control until you talk to your doctor. You may be told to not take your pill until the day you get your 'period' and then to start a new pack then. But I think your doctor really should guide you on this. How long were you on this particular pill before covid and this irregularity?
