Periods after birth control?

How is your cycle once you stop taking birth control? I’ve been on it for a year and can’t afford to get a new script, so I’ve been abstaining and using condoms when I really wanted to. Maybe had sex 3 times this month, but I’m super paranoid and want to to know what to expect. Will it come like it usually does, will it be late, early? Usual symptoms? I’ve had random cramping all month and now my breasts are sore (which never happens) and I’m breaking out. My period should come tomorrow, unless my cycle is off.
