So I am using opk's this month along with charting. Do you always see two lines on the test gearing up to the test line becoming darker than the control line. Or can you at times see only the test lines.
I just started this am and i had two lines, the test line was def lighter than the control, just curious. Also does a line tend to show up after the 4 min wait window?
It depends on what brand you're using as to how long the strip takes. There's a brand out that that even says to wait 10 minutes. I usually get a test line no matter what. I guess that means I always have some LH. OPKs are tricksy jerks sometimes. I have started splurging on smileys because it's really important for me to get the O timing just right because we are using a donor.
When I start testing I always see two lines and they get darker and then lighter after I O. If I start to test to early I won't get any lines with in the test period and then after a few hours I sometime see a very faint line
