I have ovarian cyst and had sharp pain on my left side, does this mean it has gotten bigger and burst?

I was diagnosed with a 2.5 cm ovarian cyst in Feb. 2011 and I had a sudden sharp pain on my left side (where cyst is located) and it was so bad My husband took me to er and all they said was what I already knew "That I had an ovarian cyst" so they sent me home with pain meds and told me to go to my obgyn who diagnosed me the first time. So I don't know what's going on in my body but I've got a dr apt in the morning. Can ayone tell me what to expect? thank you!
