Haven’t had a period since may 26th need answers

My last day of my period was may 26th I supposedly ovulated june 23rd or the 22nd not sure. I started testing on July 2nd which is when my ovulation strips came in they seem to be staying the same and not getting lighter but also not getting much darker. I was supposed to start my period July 8th, all my pregnancy test is taken are negative. Could I be testing to soon or could it be a hormone issue? I also got off my depo shot this year in February not sure if that could be why to. I did make an appointment but I wasn’t sure if this is normal and if someone else experienced this and can give me some answers.
