When should a teenager have her first OBGYN visit, and what does it involve?

This initial visit may not involve a pelvic exam unless there's a specific medical reason.

What can I expect during my first prenatal visit?

Your first prenatal visit with Dr. Fiedler is usually quite comprehensive, typically scheduled around 8-10 weeks of pregnancy. It will involve a detailed review of your medical history, your partner's medical history (if applicable), and any previous pregnancies.

You'll also have the opportunity to ask any questions you may have.
