Hello,
Thanks for posting your query at DoctorSpring.com
Before answering your question I would like to request you to provide me with a few more details.
What kind of a cyst was it on the ovary that was removed, do you have any details or documents ?
After the cyst removal, did you always have periods that were so irregular - every 6 months or more ?
What is your height and weight ?
Apart from your irregular cycles, do you have any complaints such as weight gain, excessive hair growth, pigmentation in certain areas etc ?
Please write back with these details.
Looking forward to hearing from you.
Regards.
