Actually hor, beside using HPT, another way is to monitor your body temp...during the first 11 days of my 2ww, I monitored..even though a bit scare to see the result lah...
My temp range from 36.8 to 37 when I first woke up, and it reached 37.3 in the afternoon..after tested hpt, I stop taking in the morning...but yesterday afternoon, itchy hand took again, it was 37.3...
