Thoughts on AF?

So I went off the pill in May after being on them for 6 years. Before I was on the pill my periods were irregular which is why I mostly went on them. Well after my husband and I decided to start trying for a baby I stopped them in May and so far no luck. But I have realized that for the fist few months off of them my periods were still pretty regular but for the past 2 months they have been back to being irregular any where from 28-33 day cycle. Could this mean the pill is completely out of my system now that it is back to being irregular and we have a better chance of conceiving? Thank you ladies!
