Idk when i ovulated but according to glow i ovulated the 18th anyways i tested with blue dye all negative what are my chances of having a positive on frer? I have had this cwhite sticky stretchy discharge since the 1ith the day it said i was ovulating and sometimes makes me feel like i started my period but it isnt. Idk what else to think. Im hoping for a positive. Please give me insight
