Is my cycle to long?

I stopped taking my birth control in August 2018 and have been trying to get pregnant since then. My cycles have been different each month ranging from 43 day cycle, 45 day cycle 34 day cycle and now going on 46 days since my last with no luck getting pregnant. Before birth control I always had a regular periods. I was on birth control for a very long time.. but how long does it take to regulate after stoping? Is this normal?
