Thanks for the query.
You once consult gynecologist and go for repeat scan to find out the present condition of the cyst
And go for CA 125 levels.
If the cyst is increasing in size and if pain aggravates better to go for removal of the cyst.
Then after surgery when the cycles become regularize, you can plan for pregnancy
Track the ovulation and plan unprotected intercourse
around the period of ovulation, that will increase the possibility of pregnancy.
