I took 2 olvulation test and the 1st one had it were the 2 lines were simular and the other test I took was where the line was lighter than the other. does it matter how my pee you pee in a cup?and it was the same brand of test I took.
How long was it you took the second test? They say you should hold urine for about 2 hours and limit liquid intake before testing again. What brand are you using?
