When Will I ovulate again?

Hi. I had a lumbar Kenalog shot on September 10th and again on October 10th. I had NO idea this would stop me from ovulating. My husband and I wanted to try to have another baby and I haven't ovulated for the past two months. I still get my period but it is very light. I don't seem to have the constant bleeding that most women have described. I'm so frustrated. The side effects from this are so awful. I has helped my pain but I don't know if I would do it again. I have had every side effect except the indentation.
