FRER vs FRRR

[twogirlsandamessyhouse]

Hi all- anyone know the difference between the First Response Early Result and the FR Rapid Result tests? Got a faint line on 10 and 11dpo on the FRER but then used the FRRR on 12 and 13dpo, and started to panic because the line has stayed faint over the four days. Wondering if the FRRR is less sensitive? (please someone put my mind at ease...)

FRRR is less sensitive - it is designed to use when your period is due or overdue. FRER is a very sensitive test which is designed for use before your period is due.

Thanks. I caved in and bought another FRER and the results were very different. Definitely far more sensitive! BFP! : )

Congratulations!
