what's going on?! please help?! is it positive? how can it be?!!! how can IB be that heavy?!

okay so i started my 'period' on saturday.... it was just pinking brown cm really when it started, then sunday seemed to turn into a normal period (mine are always light anyway)

then today it seems to have stopped... no more blood at all..... i took a test on the off chance and it's poeticise?!?! how could that have been implantation?! full red blood for one day?!?

is this really positive.. i'm terrified to test again.....
