After a GIFT procedure, calculating the number of weeks pregnant can be confusing. To determine your current gestational age, you need to count from the first day of your last menstrual period (October 21). Since it's difficult to pinpoint the exact date of conception in assisted reproductive procedures like GIFT, doctors typically use the start of your last period as a reference point.
To calculate your current gestational age, count the number of days between October 21 and today's date. Then divide that number by seven to get the number of weeks. For example, if today is November 30, there are 40 days between October 21 and November
However, keep in mind that this calculation is just an estimate and may not be entirely accurate since it doesn't account for variations in individual menstrual cycles or potential differences in implantation time.
To get a more precise determination of your gestational age and due date, your doctor will likely perform an ultrasound during your first scan on November
It's important to consult with your healthcare provider for personalized guidance regarding your pregnancy progress and any concerns or questions you may have.
