why i have two positive opk twice in one cycle?
My cycle is mostly 27 28 29 day and my ovulation day mostly between 13 14 15
I started testing from the 10th day and it came semi positive then the 11 it came more faint and the day 12 more and more faint and in 13 and 14 it came with mostly no line only control line then it became again dark and dark till the 17th day it cames very positive
I can't understand what is going on??
I knew that i can't ovulate in sperated days only during 24 hours and this happened to me in two cycles
Here is the picture the 1st test in the top is day CD10 and the last one down is day CD17

Ok well with the info provided it's easy. You ovulate on cd17! it's only positive once it's that dark and your lh through out the month goes up and down anyway so don't worry about it going stronger then fainted then bam positive xx

The last test is defiantly positive Hun, id say that's your only positive there the rest are progressing but the last one is defiantly a blazing positive,
Good luck xxx
