OPK as a pregnancy test?!?


Hi, I’m currently on my TWW. Af is due on Thursday! I have tried to wait it out for testing and even ordered tests that won’t come until Wednesday but I have been feeling dreadful and just want to know if it was AF or pregnancy! So desperate that I have googled it and resulted in using an OPK to pee on! This is a pic of it....... Has anyone ever done this and it’s been positive for pregnancy? Help!!!!! X
