Week 6 but not frequent urinating

Hi guys, im on week 6 but my symptoms is not like what i read online. So far the only symptoms i have, is nausea, crampings & swollen boobs. Ive read online that you should be urinating frequenly but i do not. Is this normal or is this meant that i have to drink more often but i think ive drink quite a amount. Im still waiting for my first prenatal so ive yet to confirm if im really pregnant from the ultrasound. But im at week 6 but still receive positive test kit
