It’s been 2 years since I’ve had a period and I can’t remember what PMS symptoms are like - so what signs will tell me my period is on the way?

I have used the pill and then my IUD to skip my period for the past 2+ years, so it’s been a long time since I’ve dealt with PMS symptoms, but I’m no longer on hormones so getting my period is inevitable. What is a sure-fire way you know you’re about to get yours? I know I’m getting it sooner or later but I want to know what to look for.
