Coming off pill

Hi, I stopped taking the pill earlier this month (Yasmin). I did this over a year ago as well but went back on it after about 4 months (not TTC) but looking back I had a period 5 days after finishing my period, then had to wait 7 weeks for my next one.

I hope that isn't the case this time as we are now TTC. At the moment glow thinks I have a 28 day cycle because of the pill. How long did it take people to get regular once coming off the pill?
