The last day of my last period was October 1st. And aside from a small amount of blood after my pap test on Halloween I have not bled at all. I've taken some small pregnancy test, the simple pink die tests, but all of them come out negative, should I take a test with a name brand like clear blue, or first response or go straight to a blood test? Glow says I'm 16 days late, so I don't understand what is going on 😓

This is the brand of strips I use if it means anything.
