Thanks for your query.
Since you have had a right ovarian cyst
for a year you need to repeat an ultrasound
of the pelvis to see if the cyst is still there or disappeared.
If you still have cyst then you need to consult a Gynaecologist in person and she will treat you for that.
If you do not have pain now or even during intercourse then you can have sex safely.
Better get examined by a Gynaecologist and she will do the needful for you and you can get pregnant after proper treatment.
All the best.
