Here I looked it up for you and this is what I found:
the pill
all you have to do to reverse the pill's effects is to complete one last cycle and then stop taking it at the end. While some doctors say women can start trying to get pregnant immediately after quitting, others are more cautious, because it may take some time for your usual menstruation and ovulation cycle to resume. If your periods are back on track, it's easier for your doctor to predict your due date and to schedule any tests you may need when you get pregnant. According to obstetrician and fertility specialist john sussman, author of before you conceive: a complete prepregnancy guide, long-term pill use has no bearing on your ability to reproduce. If your periods are irregular after you stop taking the pill, they probably would have been irregular anyway. But, he adds, if you're one of those on-again, off-again pill users, you may have to wait a little longer to resume a normal ovulatory pattern.
There you go, good luck
