ovarian cysts

so I think I have a ovarian cyst on my left side, I've had this pain for about 2 cycles, tonight I don't feel that great, I've just come home from a wedding and I'm not sure if it's my cyst or I just ate to much. I don't have money for a doctor yet so I can't actually get it diagnosed. I feel a little clammy and my left side hurts I'm on cycle day 5 no cramps just a sore ovary.
