Pregnancy Planning in Chicago
Chicago offers outstanding maternal healthcare across the city and suburbs. Once you calculate your due date, schedule your first prenatal visit around 8 weeks with your obstetrician. The Chicago area has top-rated hospitals including Northwestern Memorial Hospital (ranked among the nation's best), Rush University Medical Center, University of Chicago Medicine, and Advocate Illinois Masonic Medical Center.
Many Chicago mothers choose midwife-led care or birthing centers as alternatives to hospital births. The city has several reputable birth centers and home birth midwives serving all neighborhoods. Prenatal classes are widely available through hospitals, community centers, and private educators throughout Chicagoland.
Illinois offers paid family leave through the state program, giving you time to bond with your new baby. Calculate your due date early so you can plan your leave timeline and coordinate with your employer well before delivery. Many Chicago companies also offer additional maternity benefits beyond state requirements.
Common Questions from Chicago Expecting Parents
When should I schedule my first prenatal appointment in Chicago?
Most Chicago OB-GYNs want to see you between 8-10 weeks. Use our calculator to find your current week, then call to book. Popular practices in downtown Chicago and the North Side often book several weeks out, so call early.
Which Chicago hospitals have the best maternity wards?
Northwestern Memorial Hospital's Prentice Women's Hospital is consistently top-ranked nationally. Rush University Medical Center, University of Chicago Medicine Comer Children's Hospital, and Advocate Illinois Masonic also have excellent maternity programs. Many suburban hospitals like NorthShore and Advocate Good Samaritan are also highly rated.
Do Chicago fertility clinics calculate due dates differently?
Yes, IVF pregnancies from Chicago fertility centers like Fertility Centers of Illinois, RMA of Illinois, or Northwestern Fertility need specialized dating. Use our IVF due date calculator if you had embryo transfer, as the calculation method differs from natural conception.
How accurate are pregnancy due date calculators?
Our calculators are as accurate as the information you provide. They use standard medical formulas that Chicago obstetricians follow. Your doctor may adjust your due date slightly based on your first ultrasound, but our calculation gives you an excellent starting point for planning.
