Coming off the pill

Just wondering how long it took some of you to get your cycles regular after coming off the pill!? I've been on it for a Long time. I bled a few days after coming off of it. Then had my regular period at the time I was suppose too, but this month it's been strange. Some spotting here and there but nothing like my usually period. Could it be implantation bleeding!? Both my mom and sister got pregnant quickly after coming off the pill, so it makes me wonder?!
