IS THIS NORMAL?

Hi ladies, so I got the Mirena IUD put in in June, I got it removed in the middle of December due to me bleeding lots and pain. I went right on birth control but I started to bleed from dec 18-27th. So I went off the birth control pills on dec 20. And kept bleeding and now I’m not on any birth control. My boyfriend and I use condoms. I haven’t gotten my period yet and I’m wondering was that my period? Or just bleeding because I was on the IUD and didn’t bleed? How will I know when my period is?
