Prego?

Amber

For the first time, i tried following this app to tell me when in ovulating. I took ovulation tests which confirmed i was. As of today, i an 8 days late. My last period was from june 25th until the 1st of july. ( long one, know )

I've taken 5 clear blue advance pregnancy tests everyday since 2 days before the missed period and all of them were negative :( should i keep testing? Or wait another week?
