Bloating after period

I'm on the implant (1 1/2 year) I was a few days late and I had unprotected sex on the 13th he pulled out way before he came and on tues I started my period (normal bleeding) then it ended on the 21st but these last few days I have felt so bloated and gross 😐 does this mean I'm about to start my period again or should I be worried
