Talk to Gynecologist on Gynaecology | Ovarian Cyst

I had extreme pain during periods, doctor suggested pelvic ultrasound. An ovarian cyst was detected.It was minor doctor gave me progyluton for 21 days along with adfolic. Now i have gotten ultrasound again,the cyst is still there. I have consulted another doctor she has recommended denzen,cefspan and flagyl. And YAZ for a month after this. I have recently gotten married and I am not sure if this medicine will cause any side effects to concieve later on or not. My husband is diabetic and we want to plan baby in a month or two. We are not on any contraceptive right now, but using other ways to avoid pregnancy. Suggest me alternatives for cyst treatment.
