Losing hope and frustrated

Jessica • My fiance erica and i are trying for a baby through a sperm donor, it will be my first pregnancy!
19 days late today. Still testing negative, still having symptoms, now I'm second guessing everything though and losing hope. Have this thick gooey clearish white discharge so maybe I'm ovulating again. Even though I missed a period? I'm so dang confused and frustrated and don't know what to do.
