Hello! This is my first month ttc with the aid of opk strips. I started testing in the evening of cycle day 10. It was low. I tested morning and evening of day 11. Both low. Morning test of day 12 was almost as dark as the control line- maybe 1 to 2 shades lighter, but by the evening it was significantly lighter. Today, day 13, I tested low. Has anyone had this happen? Was that my peak? Some more info that may help... when looking at the test strip today it is definitely lighter than the control. Is it normal for the peak tests to stay darker than the control line even when dried? When looking at other women’s opk testing progression, the peak is still very obvious even days after.. Help would be much appreciated!!!
