I'm now 8 weeks pregnant & have no symptons other then my breasts being sore. Before my 8 weeks I was very nauseous & dizzy every day, all day long. This is baby #5 for me & I'm 40 years old. My other pregnancies I had symptons last throughout my first trimester. I've been reading others posts & some say they don't have any symptoms either.
It is normal and your lucky. My first two pregnancies were easy breezy but this one I have EXTREME breast tenderness, slight nausea (thankfully no vomiting), fatigue and headaches. I'd like to assume it's because I'm having a specific gender BUT I have a boy and girl and neither of them gave me these issues. Enjoy it while you can!
