Periods after birth control.

Brittany
I had completely got off birth control at the end of January this year and ever since then my periods have been really heavy and they have been mostly been going on for a month at a time I have went and seen my obgyn a few months or more back and he did tell me to call back in about 3 months if things still haven't changed and they haven't but my question is have any of you experienced this? And how long did it take for everything to get back to normal. I was on depo for about 3 years or so and the iud for 6 months. Me ans my boyfriend are TTC I'd love for everything just to go back to the way it was.
