Late & Negative

So I’m two weeks late and I’ve taken a pregnancy test everyday for the last week and it’s negative. I had brownish red spotting for a day earlier this month. It didn’t last long and I was worried it was implantation bleeding but now I’m not sure what to think. I’m no stressed than usual. Nothing has changed in my life except I stopped breastfeeding my daughter this past month and my periods have been regular for the last 6 months or so. I just need advice on if I should continue to test or just expect to get my period next month?
