I was sure I was pregnant from 6dpo, I didn't finally get an extremely faint bfp until 17dpo (4 days after af was due) so I would test again in 3 or 4 days. ... Good luck!
Praying for you too concieve and give birth :-)
I would wait a week before taking a test. Sometimes my body has delayed my period a few days. Actually, when I found out I was pregnant I thought I had just delayed my period. You'll get pregnant when you're supposed to.
