Remember that this ovulation calculator is a tool which is based on statistics. The data provided are approximate dates based on a regular cycle lasting between 20 and 35 days. If your cycle is irregular, it may be more difficult to determine your ovulation day with this calendar. In that case, we advise you to talk to your gynaecologist.

In addition, the couple is advised to undergo a fertility study if you have been trying to conceive for more than a year without success (or more than six months if the woman is aged over 35).
