my last period was December 21-27, I had unprotected sex January 19th, 21st, 23rd, & 24th. (i have it noted down in a pregnancy app) i was suppose to get my period around the 21st and it's already February, i've taken two test and they both came out negative, i know it's too early to be pregnant because it wasn't in my fertility window, but i'm wondering am i pregnant? Should i wait another week before taking a test? help?
