painful cyst on ovary. Dr doesn't care


I found out at 7 weeks I have a cyst on my left ovary. at my 9 week scan the cyst appeared larger but I'm no doctor. I have bad pain on my left side and I am not sure when to worry. I've called my Dr to follow up and I'm told if in pain go to emerge. I don't want to sit in emerge for 9 hours to be told I have a cyst on my ovary. I want to know when to worry. when is the pain too much pain. should I worry. is this normal.
