hi i was just looking for some opinions, i got the cheapy ovulation tests of amazon, + this afternoon i took 1 after holding my pee for 4hours, it was nearly completly blank on the test strip, i have just taken another + got a much more visable line it is not exacly the same as the control line which it sais it should be for a positive, just wondering if it could be 1 though? how relaible r these tests? just confused with such a difference, ino u can get faint lines which just shows the lh thats always their... thanks guys x
