Does a + on a OPK need to be as dark as the control line?

Hi Ladies,

Hope you are all well.

The title says it all really, I have just done an OPK and there is a line there although it is fainter than the control line. I've been using these tests for the last 2 months and this is the strongest (although still not as strong as the control line!) that I have had. I have had EWCM the last few days and my temps have risen slightly so I'm feeling positive.

I'm on CD14 but my last two cycles have been 39 and 40 days. They do vary between 24 and 40 days though.

Reading this back it sounds positive but the test instructions say the line has to be as dark or darker than the control line, just keen to hear your experinces.

Thanks for your advice,

Claire x
