Depending on your situation, you may need exams of your heart, lungs and thyroid. You might need a Pap test, depending on how long it's been since your last Pap test. Your health care provider might do a physical exam, including a breast exam and a pelvic exam. To find out how much weight you need to gain for a healthy pregnancy, your health care provider will measure your weight and height and calculate your body mass index. Typically, if the due date calculated with your last period and the due date calculated with an early ultrasound differ by more than seven days, the ultrasound is used to set the due date. Your health care provider can use a fetal ultrasound to help confirm the date. The due date will be about 40 weeks from the first day of your last period. To estimate your due date, your health care provider will use the date your last period started, add seven days and count back three months. Your due date also helps with scheduling tests and procedures, so they are done at the right time. It allows your health care provider to monitor your baby's growth and the progress of your pregnancy. Still, establishing your due date - or estimated date of delivery - is important. Few people give birth on their due dates. It's simply the date that you will be 40 weeks pregnant. Your due date is not a prediction of when you will have your baby. This will help your health care provider take the best care of you - and your baby. Share information about sensitive issues, such as domestic abuse or past drug use, too.
