Testing my Ovidrel shot

Fertility IG: Jazmin_lvv

Hi ladies I been testing my Ovidrel i tested yesterday and with two different pregnancy test and both came negative I tested this morning and it was negative so I just took another pregnancy test and I kinda see a faint line could it still be the trigger? Is it normal for the trigger to disappear and then come back 1-2 days later

This is the test I just took the line is super faint but it’s there
