So I need everyone's input. I am on cd17, and this is my first month off of bc. I was on bc to regulate my periods cause I have PCOS. I am also on metformin for blood sugar levels but I know it doubles up on helping regulate as well. I was at Kroger and saw several boxes of clear blue advanced opks on the clearance rack from where they has overstocked, so I figured what so I have to lose. But I have been getting the high fertility blinky smiley face for four days now. I have been testing twice a day. First thing in the morning as well as when I get home from work, around 5-6. I felt like I was going to ovulate this week. I try to keep up with other signs like ovulation pain and cervical mucus. I have had left sided pain for several days this week as well as my cm has changed to almost egg white consistency and very stretchy. Friday it was very very stretchy and wet. My cm never really gets clear but it stays a light white, seems pretty normal for me. Friday was the stretchiest and wettest that I had seen. Saturday it had went down some on the stretchy part and started to thicken back up a little. 

I'm not sure if these opk sticks can still be read like the other ones. Cause Friday night and Saturday morning the second line was close to the same darkness as the first line. And now it's lightened back up. Can these be read the same as the other ones? Or do the lines mean different things? One theory I had read was that the top line I for the estrogen and the bottom was the lh. But I don't know 

Here are my tests. Now I couldn't get a good picture, all of the tests have had two lines. But it doesn't seem like it is showing them very well. But even in the picture I can see that the one on Friday pm was almost the exact same color as the top line. 

Thoughts anyone? I could use all the help I can get. I'm new to all of the trying stuff. My DD is seven and she was the best surprise ever lol so this is the first time I have actually tried for a baby.
