Recovering!?

Hi I'm Kay and I'm 24. I had a laparoscopy July last year to remove a 10cm cyst off my right ovary. Its gone and I felt great :) my periods started being abit more regular and in December I had HSG done and my tubes are fully open. These past few days I've had severe pain on my right side as if my cyst is still there, I've a doctors appointment later but does anyone think my cyst could be growing back? I hope it isn't but the pain is like how it used to be so I'm getting kinda worried.. Will I ever be able to have children :-(
