I WAS TO GET MY PERIOD ON 20 OF JANUARY BUT DIDNT AND TOOK A PREGNANCY TEST ON THE 27 AND IT CAME OUT POSSITIVE, HOWEVER THAT SAME DAY IN THE AFTERNOON I GOT MY PERIOD. AFTER MY PERIOD WAS OVER I TOOK AN ADDITIONAL TWO PREGNANCY TEST AND CAME OUT NEGATIVE. BUT I HAVE ALL THE SYMTOMS OF A PREGNANCY. I HAVE GAIN WEIGHT, THE NAUSEA AND VOMITING AND MY BELLY IS GROWING. CAN I BE PREGNANT? CAN ANY BODY GIVE ME ADVISE?
