help needed on ovulation

[Chembolina]

Hello ladies,

I am a little confused,

i finished my period when i should of - but when i wiped for 9 days after i was still wiping pink - but when i used ladt stuff there was nothing there only when i wiped :-/

would you ladies still go off the originall ovulation and or should i do it to when i stoped seeing pink.

It was never red blood just pink

thank ladies xxxx
