Pregnant after period?

Ashley

I know it’s pretty well impossible that I am pregnant but could it be possible even though I just got off my period a week ago? I know how the cycle works and you can’t get pregnant until you release an egg in your ovulation period and that you will only possibly experience light implantation bleeding but I’m having signs even though I just had a regular period a week ago. My breast are tender, I’m nauseous, fatigued, dizzy and having a metallic taste. The test are negative. My cycle is every 25 days. Just tell me I’m crazy so I can stop letting my mind play tricks on me.
