It sounds to me like you're here reading this article because you're finally ready to take that step into parenthood.
In which case, may I be the first person to congratulate you and wish you all the very success! I remember my mother telling me about the time when she came off the pill because my parents planned to have little old me! She told me that it took over a year for he to finally be conceived and that by the end of it she was elated because she thought that she couldn't have a baby.
The fact of the matter is that after you come off the pill in most cases you'll need to give it some time before you'll be able to get pregnant.
Most doctors say that you should wait for 2 normal periods before you begin trying for a baby.
During this time you should use an alternate birth control method.
To speed up the process there are a number of things that you can do.
One of the main recommended things is to make an appointment with your GP and arrange an appointment.
Tell him/her that you are planning on having a baby and you'll likely be prescribed some prenatal vitamins designed to boost your chances of conceiving.
In most cases it will take from 2 months up to one year to get pregnant after an extended period (years) on the pill.
If after an extended period of time your periods have normalized but you are still having no luck then don't hesitate to make an appointment with the doctor; in some cases certain conditions may be holding you back.
