Acne clearing up BEFORE af....

So I'm at a loss... I know I symptom spit like crazy but I can always count on acne right before af shows... I'm 4 days away from af and my skin actually is looking really good!! Not sure if that's an early sign or not as well but seriously I always have pimples around my chin and jawline... just thought to see if any ladies had anything similar before their bfp.. I've taken 2 tests this cycle and bfn's on both, 1 was taken 2 days after ib and I took another yesterday which was 6 days after ib...
