2nd round clomid- late period

So I took a FRER at 12dpo and it was negative. I’ve taken cheap strips ever since and still negative but they seem pretty junky (scratches on the test window, evaps, etc). I’m now two days late for my period and don’t feel it coming. I had cramps the day before it was due and thought for sure it was coming.. then nothing. Should I trust the cheapies? Should I try another FR? Is my cycle just wack? I’m a testing freak and spend so much money on tests and honestly I don’t want to get my hopes up. But I really wanted this clomid to work. Thoughts?
