Having a corpus luteum cyst in early pregnancy is a normal physiological finding. There is absolutely nothing to worry about this cyst. It is one of the pregnancy changes in the ovary and has a significant role in helping the pregnancy to grow until the placenta takes over this function. This cyst spontaneously resolves (disappears) later in pregnancy. It does not need any treatment.
It is (obviously) reassuring to note that the fetus appeared normal for its (gestational) age.
The minimal subchorionic bleed that was noted on the scan is not uncommon to find in early pregnancy. Over 90% of women with this finding, in the presence of normal fetal heart rate go on to have a normal uncomplicated pregnancy. This is true even if you get slight bleeding in early pregnancy.
