NORMAL? OR NAH?

Is it normal for a pregnant woman to have head aches, dizziness, or migraine? Because personally,I am feeling dizzy with a little head aches 3 to 4 times a day. Please help me? I really don't know what to do. And one more thing, I am also experiencing something odd with my right breast that felt like there is someone who pointed at it and left an after feeling (like an after shock feeling)
