I have a question that I am somewhat embarrassed to ask as I feel I should already know the answer...

Not to mention, I've heard differing opinions in the past regarding this topic and would like some clarification. My question is: Does taking birth control pills for an extended period of time (say...longer than 5 or 10 years, for example) adversely effect a woman's fertility? The general consensus I've come up with is "no", but I have heard other opinions as well. I'm torn as to what to believe because I could see fertility being effected since BCP suppresses ovulation, basically telling the body "you're already pregnant, don't ovulate." Could it then possibly cause an issue once a woman goes off the BCP and wants to ovulate and become pregnant?
Any information, personal accounts, or patients with an issue similar to my hypothetical would be greatly appreciated. Thanks!
