Unsure of pregnancy

I’m experiencing this currently. Took a pregnancy test 2 days before my missed period, and it was negative. And it’s going on 3 days without my period , should I test again, I also feel period like cramps but no period. I’ve been having milky white discharge and watery like discharge, feels wet like I’m on my period but when I check it’s just watery discharge. I’m trying to wait until the week is up to test again, I’m so anxious because so far I haven’t gotten my period yet.
