Hypo-Thyroid and Ovulation

I have hypo-thyroidism. In January, my thyroid level was 9, in March it was 7, now its 4.2, so it's getting better. I've had 2 periods since Januray. The first cycle was 56 days long with a short, light period, the second was 57 days long with a normal period. I have 2 questions, 1) I don't think I was ovulating with those long cycles, but still got a period, is this normal?

2) Shouldn't I be ovulating again since my levels are getting lower? and if I'm not, could this be indicitive of another problem?
