Collapsed corpus luteum (left ovary)...? What does this mean

Tamera • Happy Mother To Be. Due: 24th December. In all praise God 🙌🏾❤️👶🏽👣💕
When I went for my scan at five weeks and 5 days. They said everything seemed to be fine. But they just don't know how far I am so will need to come back next week. Then looking at the notes I saw collapsed corpus luteum. What does this mean?
