Could it be?

12 dpo BFN

17 dpo faintest postive

19 dpo today, No periods yet.

Do you think i could be pregnant? When should i test again. Period was due on 14dpo but once in a while my period gets delayed by 5 days sometimes a week. Dpo's are correct as i was using opks.

I was thinking by 17dpo line should have been darker so may be it was an evaporation. I posted a poll for that also and 70% said positive. So do you think i could be pregnant? When should i test again.
