Its Been 6 Months Since I Had A Benign Tumour,

Its been 6 months since I had a benign tumour, right ovary and tube removed. I have recovered fairly well but I am experiencing quite acute pain in the area where my ovary used to be at about the middle of my cycle. I manage this with neurofen. Is this normal. I guess I would consider it to be ovulation pain but I don't have an ovary any more so I'm confused. Thanks, Amanda
