OBGYN - APGO Notes crc

2 cm subserosal fibroid in a pregnant woman at 17 GA, further eval?
No further eval. Although fibroids may demonstrate red or carneous degeneration with rapid growth, this is uncommon for smaller fibroids. Uncommonly, fibroids can be located below the fetus --> C-section. If the fibroid were causing symptoms such as pain or is in a concerning position, it would be good to follow its growt
