ovarian cysts

Have ant of you ladies experienced ovarian cysts? I've had them a few times before but never like this! I had my period 2 weeks ago, it was oddly light and was a short cycle. Yesterday I was sick all day at work- stomach troubles had me in and out of the bathroom. I figured it was a stomach thing going around or something that I ate. Today I woke up exhausted and horribly dizzy .. so I called off work because I felt feverish too. The cramps are HORRIBLE! It's pinchy, achy and alternate from side to side. My back is sore and even my hip and thigh muscles are achy too. I called my gyno, I won't have an ultrasound until tomorrow. Have any of you had it this bad? I'm scared because I've never had it like this before.
