Can Taking Klonopin Cause Delay In Periods?

I ve been on klonopin .5mg twice a day for just over 2 months. I have not had a period and I m 45 days late. I have my tubes tide and have an iud in place and have had regular periods up until this point. Can the klonopin be doing this. Other than the medication change my eating and excerising ha its have not changed.
