Smoking Uterine Surgery such as fibroid removal In Vitro Fertilization (IVF) Diagnosis: Second-Trimester Ultrasound (18-20 weeks): Placenta previa is more commonly identified during the mid-pregnancy ultrasound, usually around 18 to 20 weeks. However, some cases detected at this stage may resolve by the third trimester as the uterus grows and the placenta moves away from the cervix. Third-Trimester Ultrasound (28-32 weeks): If placenta previa is suspected or diagnosed earlier in the pregnancy, follow-up ultrasounds are typically conducted around 28 to 32 weeks to see if the condition has resolved. Persistent placenta previa at this stage is more likely to continue to term and require special management.
