Implanon Removal After Effects

So I had the Implanon rod for 6 months and I ended up gaining a lot of weight and my mood swings were really bad therefore I got it removed in April. 
Since then ive been bloated all the time and I've had 2 regular periods (on time ect), 1 period that was 8 days early and now my current period is 4 days late :( I don't know what's hapenning and was wondering if anyone experienced or is experiencing the same? 
What did you do?
