I Have Been Super Super Horny. Like It's Almost To

I have been super super horny. Like it's almost to the point of driving me nuts. And all week I have been very nauseous until around mid-day then it goes away. i have had a headache everyday this week. I also have been haveing a weird feeling in my lower abdomen. I should mention I have pcos and do not have regular periods. But is it possible these are signs of pregnancy?
