TTC question

I'm 31 years old today and ttc. I'm due for af early next week. We focused on my ovulation week this month. This past week, I've had some random waves of nausea, a random fever and my appetite has been off somewhat. I woke up at 3am this morning with a numb and somewhat restless feeling in my legs, which was extremely random. I don't have any other symptoms. How soon should I expect the classic pregnancy symptoms? Does everyone get them? Is any of what I'm feeling a good thing or am I making a big deal out of nothing?
