No period for a month now .

Has anyone gone through this .

I haven’t gotten my period for a month . I never skip . At all . But I’ve taken 4 pregnancy test and they come out negative .

I have lower back cramps , little upset tummy almost nauseated , I frequently get dizzy and extremely tired . At the same time I feel like I’m on my period but it’s clear watery discharge . Anyone ?

I will be seeing the doctor on Monday but I’m just annoyed and upset . Would of loved being pregnant.
