Any thoughts?

Can ovulation cause mood swings? Has it ever happened to you? I'm supposed to have just entered my ovulation window. Usually, I get moody (hell, let's just call it like it is. I get down right short tempered over the smallest of things) right before my period. I meditated earlier today in my candle lit bubble bath while listening to the sounds of nature - rainforest on YouTube. It was so relaxing. I was at such peace. But then, about an hour later I got short tempered with the wind blowing (the fricken wind!!! Of all the random things to set me off). Ever since, I've been a bit of an a**hole and I just don't understand why I'm so aggravated. I sometimes get this way when I start coming down with a cold, though, I have a strong immune system and rarely find myself sick. Could I have a hormonal imbalance that I'm not aware of, perhaps? Anyone else ever get this way and found out why? Been TTC for going on 8 years so I doubt that I'm already pregnant and just don't know it. I'm pretty in tune with my body. This just has me baffled.
