I'm so confused 😖

So 04/16 AF came and left...then she came back on 04/28 ... So I figured maybe on the 16th I was just spotting cause it was very short and medium. So I was currently in my TWW and she came back this morning 😭😭😭 ... I'm so confused ... When you first get off the pill is it normal to have more than one period a month? how do I even track my ovulation now ?
