Urgent Gynae appointment for Ovarian Cyst

Hi guys

I'm new to this so bear with me. I had a pelvic scan a week ago and was told that I have an ovarian cyst on my right ovary and that it's putting pressure on my kidney! Dr made me an urgent referral to gynaecologist and I had bloods taken which came back normal. My appointment is on Tuesday, what should I expect? I am 30 years old and would like more children. It's worrying me a little. Any advice or personal experiences would be much appreciated x x x
