HI . I TOOK THREE HPTs. ONE MONDAY . ( TOO EARLY ) SO I RETESTED TWICE . ONE ON A WEDNESDAY && ONE ON A THURSDAY . I TOOK BOTH OF THEM EARLY IN THE MORNING WITH MY FIRST URINE . THEY WERE POSITIVE . THEN , FRIDAY , I WENT TO THE CLINIC && THEY GAVE ME ONE ( AFTERNOON ) && IT CAME OUT NEGATIVE . MY TOM TOM WAS SUPPOSE TO COME ON THE 18TH BUT IT CAME TODAY ( 21ST ) . BUT MY PERIOD DOESN'T LOOK NORMAL . IT'S WAAAY LIGHTER THAN USUAL . WHAT COULD THAT POSSIBLY MEAN ? MY MOM HAD A PERIOD OR " BLEEDING " FOR THOSE WHO SAY YOU CAN'T GET YOUR PERIOD THROUGH PREGNANCY .
