i came on my period 10 days early, but before that i have been showing signs of being pregnant. I still get headaches a alot. lower back aches, sore boobs, sensitive nipples, nauseated, im eating more, im always moody now, it's been hard for me to go to sleep, and i have been cramping. It took a pregnancy test but it was negitive. My boyfreind thinks i took it too early. Even though i came on my period, is there a chance that i am pregnant?
