How do i know if i had a follicular cyst or a corpus luteum cyst.?

Unnecessary to know: They are two phases of the same thing. An ovarian follicle should rupture releasing an egg. If this doesn't happen, the follicle keeps enlarging turning into a cyst. The ruptured follicle is called the corpus luteum. If the escape opening seals off, fluid can accumulate causing a corpus luteum cyst. An ultrasound may determine which you have but it isn't important to know; they act the same.
