is this weird?

[Jennifer.]

So I'm never faithful with continuity taking opks every morning but I put my foot down this month and am doing it...I've taken 3 so far on CD-5, CD-6, and CD-7 but there is a pretty dark line already (not positive) is it still normal to have a pretty dark line on only cd-6? I'm an opk newb so sorry if this is an ignorant question.

here is a picture of the 3. The top is from today (cd-7) middle is cd-6 and bottom cd-5. is it okay for the line colors to fluctuate before you get a positive?

I'm just weirded out because I remember testing at like CD-15 and the line being just as dark as the middle one..

The color in my lines keeps going up and down too.

Mine did that for a while too. I tested every day and it got pretty dark one day and then back to the usual back and forth somewhere between 25-50% dark. Then one day I got a really bold positive. I'm 4dpo now, so I think its pretty normal.

Some women get a nice fade in and out pattern, but I guess not us!
