Skyla & bleeding

I got the Skyla placed on July 7, and my period ended on the 9th, like no blood what so ever. Just now, I'm sitting here having cramps like I'm beginning my period all over again, and I go to the bathroom and check, and low and behold, I'm bleeding-heavy. I tried calling my doctor and no ones picking up.

Is this normal after just getting the Skyla placed?
