Pregnantor Funky PMSing?

I hope that somebody has been through this before, and can confirm it’s probably just PMS!

I started having period symptoms two weeks before my actual period date, which is due in 9 days.

Basically, my boobs are swollen and painful, I sometime have cramp-like feelings in my abdomen, and I have some white secretion.... I took a pregnancy test which came out negative, but since my period is still some days away, it could be that it was too soon to show on the test!

Has anybody ever had such early period symptoms? I always have regular cycles and symptoms between 1 week to only a few days before my period, and I’m getting extremely anxious.

As I wait for my period (and another pregnancy test in a few days), any advice is appreciated!
