Confused

Jessica • Mommy of 2 ♥️
So lately my stomach has been bloated and I have been feeling nauseas (but haven't thrown up) I'm having low back pains and have been feeling sharp pains in my stomach and my appetite has also increased and I've been super sleepy. I took a pregnancy test today but it came back negative. My period is due on Tuesday. Can these symptoms be because my period is coming in 3 days?
