Dilemma...

Hi, I missed my periods and had got all symptoms that a primi gets . Sometimes I get Morning sickness and some days I am okay . I get bad mood swings and can sometimes feel cramps in my tummy, feeling urge to pee, migraines during night,bloating and fullness in the tummy always and size of tummy also increased and I lost weight also . I took HCG test thrice and shows negative which was 20 days post LMP . My cervix now shows 1cm dilated and white creamy discharge. Need suggestions on this . When should I check my test again ?👩🏽‍🦱.....
