In simple words: The placenta partially covers the cervix during the second trimester of pregnancy (weeks 14-27), but there's no bleeding.

Partial placenta previa without hemorrhage, occurring during the second trimester of pregnancy (14 weeks 0 days to less than 28 weeks 0 days).

Example 1: A pregnant woman at 20 weeks gestation presents with painless, bright red vaginal bleeding. An ultrasound reveals that the placenta partially covers the internal os of the cervix, confirming a diagnosis of partial placenta previa without hemorrhage., A routine ultrasound at 18 weeks gestation shows a low-lying placenta. Follow-up ultrasounds at 22 weeks and 26 weeks confirm it to be a partial placenta previa. The patient is advised to avoid strenuous activity and sexual intercourse., A patient with a history of partial placenta previa in a previous pregnancy undergoes an ultrasound at 16 weeks. The ultrasound reveals a similar placental position. Close monitoring is initiated, and a plan for a repeat ultrasound in the third trimester is made.

Documentation should include ultrasound findings confirming the partial covering of the cervix by the placenta, the absence of hemorrhage, and the gestational age (specifically within the second trimester). Any associated symptoms, such as cramping, should also be noted.

** This condition can resolve on its own as the uterus grows during pregnancy. Regular follow-up ultrasounds are crucial to monitor placental position and potential bleeding.
