Step 1 of 6 — Your History

Have you ever delivered a baby preterm (before 37 weeks)?

Step 2 of 6 — Cervix

Have you had any procedures on your cervix, or have you been told your cervix is short?

Some cervical procedures and a short cervix can weaken the cervix and increase preterm birth risk.

✓Told I have a short cervixEither in this pregnancy or a previous one

✓Had a D&C or multiple D&CsFor miscarriage, abortion, or other reason
