Too Anxious To Wait!

Olivia • Happily engaged and expecting our first baby♡
My fiancé and I had been TTC since my firtle window started. (January 24th) and we've been doing it everyday almost twice a day, and my most firtle day (the 28th). I'm getting way too anxious! My stupid self got a box of First Response tests, and of course it was negative! How long should I wait to test? AF is due on the 19th.
