Irregular periods

Ive always had irregular periods even while on BC. I stopped taking BC April of 2016. I've recently been tracking my cycle and it's anywhere from 50-60 days long. I just had a period September 12-18 and started again on Monday, the 2nd. That's only 21 days from my last period. From September the 19th through October 1st I used OPK's everyday and never had a positive LH surge... Am I not ovulating at all? Does anyone else have similar problems? Any suggestions or incite?
