Help!!

Lorelai

I am 7dpo idk if I can take a pregnancy test or not but I’m drinking water like crazy (I hate water), the smell of chicken makes me sick, and I’m craving cheese and chocolate (I hate chocolate too).... these were all symptoms I had during my other pregnancy... but idk which test to take and when I can or should take the test????? I’m also so terrified for it to be negative
