Is she pregnant?

hi everyone,umm ok my girl missed her period monday and today is the next monday 7 days later,now I gave her a pregnancy test saturday but nothing came up but negative well I could barely see the negitive symbol, soo I figure hey shes not pregnant,but yet I see her size getting a tabb bit bigger,her breast become sore from time to time,shes been sick off and on for the past few days having very bad bad migrains,she says she hurts all over,shes been on a eating freinzee like bad,always hungry,I dunno what else tho could she be pregnant even the test could be wrong or what????? being pregnant can cause migrains I mean the kidn where she locks up and cannot move ,????????? did she take the test too soon/????????????????please help thank you we had sex 2 weeks before her period jsut so it may help with your info

EASIER FOR YOU TAKE THE DAMN TEST AGAIN!!!USE CONDOMS...OR DONT C*M IN HER....BUT I DOUBT THE SEMEN IS STILL ALIVE...AND HER BREASTS ARE PROBALLY JUST GROWING OR SHES SICK....AND GROWTH-SPURTS CAUSES HUNGER AND PAIN ALL OVER YOUR BODY SO ITS MOST LIKELY JUST THAT.TAKE THE TEST AND YOULL FIND OUT
GOOD LUCK
