Really long cycle (45-49 days)

Hillary
Does anyone else experience really long cycles? I was on birth control for 5 years and I stopped taking it about 9 months ago. My first few cycles were average (30-33 days) but for the last 6 months they have been between 45-49 days 
I feel like something might be wrong. I'm going to check with my doc but I don't have an appointment for a few more weeks.
