Hi everyone, so I did my first OPK not expecting to see anything (I did one for fun last month when I bought em to see how they worked). But there is a very faint line (I think I hope it is there for you to see and not wishful thinking). I know it has to be darker then the control but does a faint line mean my LH is starting to surge?! I'm testing tomorrow and the next day etc until I get a dark line. Thoughts? ​​
