OPKS I am so confused *newbie*

[psychnurse]

I am 8 days post mirena removal. Got my period the whole 4 years I had Mirena. Am suppose to get AF in 5 days according to my LMP. Used an opk last tues and got two lines, one fainter than the other, same thing wed. Thur Fri Sat Sun and Mon only got one line on OPK... now this morning got two lines again, one fainter than the other. I know when the first line is darker than the second that means a (+) but is the first line suppose to just come and go? Sorry this is my first time using OPK

Yes, your LH levels will go up and down throughout your whole cycle. It's only + if the test line is as dark or darker as the control line. Totally normal. Here is a pic of my + OPK from yesterday
