Pregnancy Date Calculator
Use this calculator to determine your due date or the date your baby was conceived.
To determine your due date, enter the date of your last menstrual period. If you already know your due date, you can enter that and "calculate backwards" when conception occurred. The bottom part of the form tells you how many weeks pregnant you are today or on the date of your choice. You can also determine on what date you will be the number of weeks pregnant that you enter.
Keep in mind that this calculator is based on a 28-day menstrual cycle, and might not be accurate for women whose cycle varies from that schedule.
How your due date is calculated:
Your due date is estimated by adding 40 weeks (280 days) to the approximate first day of your last menstrual period. Only 5% of women deliver their babies on their projected due date, so this date should be used as an estimate - it is not an exact calculation.
(Days of the week are optional. The calculator will automatically determine them.)
PreferaOB is a prescription multivitamin / multimineral nutritional supplement indicated for use in improving the nutritional status of women throughout pregnancy and in the postnatal period for both lactating and non-lactating mothers. PreferaOB™ is also beneficial in improving the nutritional status of women prior to conception.
PreferaOB is rich in iron and smaller than most prenatal vitamins, making it easy-to-swallow. Plus, PreferaOB includes vitamin B6 which may reduce likelihood of pregnancy morning sickness2 and comes complete with 1 mg folic acid.
Ask your doctor if PreferaOB is right for you.
