How long till BFP??

What’s the latest people have gotten their BFP??

Currently 4 weeks 2 days post HSG and my tests are just weird and unclear. On previous posts people saw vvfl and now I see nothing when taken with fmu.

Anyone share some information please!? I don’t know what’s happening or what’s going on. I have no symptoms of AF showing and none of pregnancy. Even my partner hasn’t had his usual spot break out before my AF arrives. Glow said I should have stared yesterday but I haven’t pinned it down until around August 4th.
