IB or AF? Help!

Help! I am going crazy. Cd 33, it is are usually only 25-28 days. according to glow I'm a week late. Spotting just started today when wiping but now a few hours later seems as tho it's going away, I will post pics of both. I don't even know what to think, just a waiting game at this point. I took a test at 3 and 4 days late, both negative. I am currently waiting until AF completely shows her face and if she doesnt, I am testing again Sunday (which would be 3days after possible implantation?) Pictures are posting weird, pink one was first.
