Could this be the month? I am praying so hard!

This tww has been the most difficult of all. We’ve been ttc for over a year and if we don’t conceive this months we will be starting the process of IUI. AF usually would come today, so I’m praying it doesn’t so I don’t have to go through the process. So far, no signs of AF. I have been taking a pregnancy test almost every day for 6 days with no hint of a second pink line. Even though when I stair at it long enough I can trick myself into seeing one. I really haven’t had any symptoms but as long as AF stays away there is still hope!
