Don't feel pregnant!!! Is this normal

Any advice would be so appreciated. I'm 6 weeks and 4 days pregnant. I started out a week before finding out with heavy cramping. Which has each day gotten better. Every now and then I'll have a little cramping not much. I've had off and on breast tenderness and they feel bigger. I'm also bloated, tired, sometimes nauseous, and have a few migranes. Other than that most days I've felt great but with my daughter I threw up my whole first trimester. Has anyone else felt not pregnant due to hardly any symptoms? Thank you
