To early?

So I took a test 1 day (11.13) before missed period & it was negative. And it’s (11.15) currently & still no period. Going on 2nd day.

I have regular periods and never miss any. I had back aches, mild stomach cramping that comes and goes. Only symptoms I’ve had thus far.

Was it to early to test? The test I tested with didn’t say I was able to test 6 days sooner like first response (the one I usually get, but in this case didnt)
