Don't feel pregnant

Dedwards
I know I really shouldn't be complaining, but I'm a little worried. I got my BFP on February 1st. For about a week before that and then for a few days after that I was dizzy, and nauseous, had tender breasts, was super constipated, and extremely tired. But since then I feel nothing except a little breast tenderness here and there. Today I'm 5wk +5.  Is anyone else feeling like this? Is it something to be worried about? Should I maybe test again?
