Ovulating or something else???

Katrina • I lost my right ovary and tube due to a large cyst that ruptured had a tubel ligation reversal done on April 24th 2015 for my left tube. We are now ttc.
I have this uncomfortable pain in my left side around where my ovary is. It's pretty uncomfortable could I be ovulating or could it be something else? I had a tubel ligation reversal done on April 24th. And only have one ovary and tube and it's the right one.
