6 days late...

So it’s our first month of trying and I’ve read all the advice ..seriously everything. I’m 30 and I wanted to not only be informed but also I want to get pregnant quickly. So now I’m 6 days late on my period ..took a pregnancy test on day 5 of being late and it was negative

I called my obgyn nurse to get advice and she said to give it another week and if still no period or positive test I should come in and do a blood test

Hers my question: has anyone else out there found out they were pregnant after having negative tests and missing their period for a week?
