Hello, I have some questions regarding an OPK. I am TTC #1 this is my 4th cycle trying. I decided to add OPK this month, as I was not officially sure when I was ovulating and was just going off of Glow. I am on Cycle day 11 which seems early for peak fertility.  However, I started testing with OPK on Saturday and glow is saying my fertile window starts today. This morning on my OPK I received a peak result, just a solid blinky smiley. I never received any high fertility days prior. Is that normal? Could I be ovulating too soon? Any feedback would be greatly appreciated.
