If the baby is due in February next year, in which month should conception occur this year?

If you plan to deliver your baby in February next year, based on the date of your last menstrual period (LMP), conception would typically occur in May this year. However, if your menstrual cycles are irregular, the estimated due date (EDD) cannot be calculated reliably from the LMP. Details are as follows:

Generally, a full-term pregnancy lasts 280 days (40 weeks). If your menstrual cycles are regular, the EDD is calculated from the first day of your last menstrual period: subtract 3 months (or add 9 months) and add 7 days. Therefore, to deliver in February next year, conception should ideally occur in May this year.

If your menstrual cycles are irregular, the EDD cannot be accurately determined from the LMP. Instead, early-pregnancy ultrasound is typically used to estimate gestational age and calculate the EDD. Thus, women with irregular periods who wish to deliver in February next year should consult a qualified healthcare provider at an accredited hospital for personalized preconception guidance and fertility planning.

It is recommended to take low-dose folic acid supplements during the preconception period to prevent neural tube defects, continuing through the first three months of pregnancy. Additionally, avoid tobacco and alcohol, adopt healthy lifestyle habits, and refrain from exposure to ionizing radiation or hazardous chemicals during the preconception period.
