Hi, On December 14 I Had Laparoscopic Surgery To Remove

Hi, on December 14 I had laparoscopic surgery to remove a large ovarian cyst, and ended up losing my left ovary and Fallopian tube as well. I was on my period at the time of the surgery, and it continued for a few days after. I've been done for a few days now, but now I'm having light spotting. Is this related to my surgery? Is this normal? Also, I skipped my November period, and my December one was extra long and heavy, but with no pain (which is very abnormal for me). Trying to piece this all together!
