Hello,
The cystic structure in right ovary, as has been mentioned is
corpus luteum.
Corpus luteum is normal in early
pregnancy, in fact it is the cyst which supports early pregnancy by producing hormones till the placenta is formed and starts functioning.
It is formed after ovulation. So, in all probability, you had ovulated from right side.
I would like to know, why are you so sure that you ovulated from left, was the cycle monitored by follicular study?
So, dont worry about the cyst.
The chances of ceserian due to this cyst is nil, as this will regress once placenta starts functioning and due to other causes can not be discussed at present.
Hope this clears your doubts.
If you still have any other query, do write back to us.
good luck.
Dr. Mrs. Sumeet Baheti
