A-Assurance and follow up on next visits
C-Surgical removal of the cyst

E-Wide spectrum antibiotics to prevent infection
This cyst is most likely the corpus luteum of pregnancy. It is significant for sustaining pregnancy through production of progesterone. Assurance and follow up for size and symptoms is recommended in the first trimester.
