After The Pill..

Hi ladies! I was just wondering how long did it take for you to get pregnant after you came off your birth control? Currently I'm taking it in pill form. I'm not sure if it makes a difference as to what form of BC you take, to how long it takes to conceive. My husband and I plan to try for our first baby around this time next year. I have a follow up with my gynecologist in august. I just want to make sure that I'm off the pill long enough for my body to still have its cycle without the help of BC. I have very irregular periods.
