Ovarian cyst pain

The last time I went to the dr I was diagnosed with a small 2cm ovarian cyst (not sure what type) but ever since then I've had really bad pains in my right ovary that have progressively been getting worst and it's messing up my menstrual cycle and making it irregular and I have a feeling its growing because there is pain there when my gynecologist told me most times girls don't feel their Cysts.. I feel pain during intercourse with my boyfriend and I'm also really nauseous and have been throwing up... has this ever happened to anyone and their cyst grew bigger and they had to get it removed.. or something else. I just want to find out what might be going on with me
