Hi Im TTC and im not due my period until the 21st. Im wondering if there is a pregnancy test i can take when only 1 day late? I read about it somewhere, and I know that normally you have to wait at least to be 4 days late but im soooo impatient to find out!!! THANKS!! If a 1 day late test exists, does anyone know makes of the product or names etc? THANKS!!!
