HER2 tests keep failing

I can't seem to get an answer on my HER2 status and it's bugging me.

So here's what happened...

Biopsy IHC results were equivocal, FISH test attempted, but there was not enough material to complete it.

OK, fine, proceed with lumpectomy and we'll test the tumor.

Surgery successful, got the whole thing with clear margins. Let's test that puppy and see what's what.

Again, IHC results equivocal, FISH test now underway.

My status is T1aN0, grade 1, ER+ PR+ HER2?????? Grrr

I realize that because of the rest of my cancer features, the HER2 answer probably won't affect the course of my treatment, but I just wanna know, ya know?
