Pregnant ?

For about some weeks now I've been paying close attention to my body I seriously feel like I'm pregnant. I'm a regular coffee drinker I love coffee but last week I've notice when I drink it I've become light headed and dizzy I'm a day away from AF but no signs that it's coming on. my nipples feel tingly like they are growing and my breast feel real sore . And I get super nausea throughout the day
