OPK 7 days before period is expected,

Sam

So I have heard you are able to tell if you’re pregnant by testing with an OPK and I just wanted to have a little look and to my surprise there was a fairly dark line (considering there would normally be no line) I just wanted everyone’s opinion tbh what do you think??? This is my OPK (I took it about 2 hours ago it hasn’t changed much other than the test line getting a little lighter and not as bold
