I am only 5w1d, but found out I was pregnant at 3w3d. Week 3 and 4 I felt awful, breast tenderness, headache, nausea and extreme fatigue were almost constant, but lately things seem to be calming down. My breasts still hurt a little, but not nearly as bad as before and I haven't had any nausea in a couple of days. Is it normal for symptoms to let up or is that something to worry about? I know it is still really early, but the change in the way I'm feeling is nerve-raking.
