Early pregnancy symptoms

Hey mommies! I just turned positive last wed (week 4) as i was experiencing some giddiness and nausea. I didnt feel any cramps or so. However, as the days go by (week 5) I realised i no longer felt dizzy or nausea anymore. Instead i experience some mild cramp on my lower abdomen. Other than that everything felt normal. I only schedule to see the gynae on week 6. Is this kind of normal? Or should i be worried that i no longer felt dizzy and nausea? Is cramp normal too? Getting a little paranoid as this is my first. Thanks in adv
