What you need to do before baby, broken down by trimesters and weeks.
Week 14 Sign up for a prenatal-yoga class. Yoga can build strength for labor and help improve your flexibility, agility, balance and posture. You're probably also ready to start shopping for maternity clothes.
Week 15 Ask your doctor about the multiple marker test, which screens for chromosomal abnormalities, neural-tube and other defects; it's normally done between 15 and 20 weeks.
Week 16 Begin to think seriously about how you want your labor and delivery to play out. To get started, and to set up a birth plan, visit our Labor & Delivery Guide.
Week 17 Tell your employer you're pregnant if you haven't already done so. Be ready with a plan for your maternity leave as well as ideas about who will cover for you during your absence.
Week 18 Between weeks 14-20, your doctor may order an amniocentesis if you're 35 or older to screen for chromosomal/genetic disorders including Down syndrome and spina bifida.
Week 19 Decide whether or not you'd like to know your baby's sex. Many doctors do a detailed ultrasound between 16 and 20 weeks, at which time gender often can be determined.
Week 20 You're halfway there! Time to take a tour of your hospital's maternity ward.
Week 21 Though your due date sounds very far away, start reading up on baby care now. You won't have time after your newborn arrives.
Week 22 Think about whom you want present at your baby's birth, and begin discussing it with family.
Week 23 Sign up for a childbirth-education class, as they fill up quickly. Choose a session that you can complete before your 36th or 37th week.
Week 24 Start shopping for baby furniture and nursery accessories. (Leave painting and furniture-refinishing to others; fumes can pose a hazard.)
Week 25 Craving a babymoon? Do it now.
Week 26 Between weeks 26-28, a glucose screening is offered to all women to test for gestational diabetes.
Week 27 Look into child care if you'll be returning to work. Day care centers fill up fast, and nannies can be hard to come by.
Week 28 Your doctor or midwife will want to see you every two to three weeks starting at around week 28. Right now, you may want to think about getting a life insurance policy and a with a guardianship agreement.
