first response early result is known to be the most sensitive test OTC.

Ive known many peopel wiht dollar store tests and theyve had a lot fo trouble wiht them. one woman's even turned positive--when her husband peed on it!!!!

all that being said, my cousin was trying for about 5 mnths...she finally found out she was pregnant via an OTC. then she went to the doctor and it turns out she was 2 months along!!! she tested negative for nearly two months before the OTC was positive! so it is possible. and the docs were right...(her periods were irregular too)

GOOD LUCK!!!!!!!! let us know...
