odd ovulation symptoms

[Aunt MehMeh]

So I think I ovulated earlier this week. On Tuesday I has pressure and pain in my right side (pelvis) and I knew that was my cyst or ovulation beginning. Then as I was sitting and the computer at work the skin on my lower back flushed on and off several times. I was cold everywhere else! Also all that day I was lightheaded and slightly nauseous. Anyone else have this happen? Could it just be hormones?
