No period yet but negative test

Robyn

Hey i need advice. I stopped my birth control August 1. Really working towards TTC for the last two months. My period did change dates last month since ending my pill. But this month i should have gotten my period either last Wednesday or this past Saturday, but nothing. I took a test from my ovulation kit which was an HCG test, and that came back negative on Saturday.

Do i take another test? Is this normal?
