Hello,
Continuous use of contraception has not proven to decrease fertility. No longer having a "period" will not further affect fertility. In fact, even users of oral hormonal pills, who have 7-day breaks without hormones, do not menstruate. In fact, if the use is impeccable, ovulation is dormant even in these users. It is therefore bleeding called "withdrawal" that they have each month and not menstruation.
Thus, it is indeed expected that fertility is restored following the cessation of hormonal contraceptives. However, the ovulatory cycle can resume its normal course up to 3 to 6 months after stopping. This should be taken into account when planning to have children. It should also be noted that several factors can contribute to decreased fertility (smoking, alcohol, age of the woman at conception, family history, etc.).
For your information, I also invite you to read a very interesting article by a pharmacist specializing in women's health, clinical professor at the University of Montreal and former Vice-Dean of the Faculty of Pharmacy at the University of Montreal:
I hope this answers your question.
