Conceive for Women is designed for women who are having difficulty conceiving and that can happen for any number of reasons. Some of which, like having irregular cycles, are more obvious than others. If you've already experienced a longer than usual time to pregnancy, then Conceive for Women may be a useful strategy to shorten that time period.
If your cycle is already like clockwork, you may experience some variation in the timings of your cycle for a few months. This only happens to a small percentage of women who have regular cycles and it might not happen with you. Unless you find you are getting a shorter than normal luteal phase (the time between ovulation and the first day of your period if you are not successful in that cycle should be 10 -14 days in length) then this is nothing to worry about and it should settle down after a month or two.
If after 3 months your cycle has not settled in to a regular pattern, then we would suggest that Conceive for Women may not be appropriate for you. Although FertilitySmart Conceive for Women is safe, gentle and effective, it will not work in exactly the same way for everyone.
