Is it possible

Is it possible to still have pregnancy symptoms after you get your period. I thought i was pregnant but then i thought it was just me getting my period. I got my period but i still have the same symptoms. Im getting nausea all day, certain smells make me nausea, im getting headaches, im always hungry, im starting to get a bloody metallic taste in my mouth, i have more mucus than usual and im like extremely tired i can barley get out of bed in the morning. I've already tested twice, i got negatives both times. What do you guys think?
