hi all! this is the first time ive been using opk tests to get preg so i need some advice! i have been taking the first response opk tests and they have gone from light to dark, then light again and this morning dark again! im assuming my surge was last night and this morning! well i was almost out of tests so i bought some more and bought the clearbkue digital ones. i took one when i got home and it was negative, no smiley face. i felt that it could be wrong because i just had had a positive so i took my last first response and it was positive! whats going on? just to make sure i took another clearblue, and it was again negative! has this happenned to anyone else? it shouldnt matter what test right, a surge is a surge no??? sone advice would be great!:-)

the surge only lasts for a few hours, though. So it could well have passed by the time you took the CB digi. Also the FR might well be a bit more sensitive than the CB.

Either way, I hope you're getting jiggy
