I Just Had Laparoscopic Surgery Two Weeks Ago To Remove

I just had laparoscopic surgery two weeks ago to remove some of my endometriosis. I was a stage one two years ago and it's advanced to a stage three. Not all of it was removed because it couldn't be removed safely. I was told I was going to have a period right after my surgery and I did, I had my period for five days. I just started my period again and have been severely cramping and have been bleeding heavily and have been having huge clots. Should I be concerned or is this normal?
