Ovulation test help me understand

Robin
This is my 2nd month ttc. I just finished my 28 day cycle yest ..Monday. I took the ov test at five in the pm. It had the control line and a very faint line on the bottom. What I want to know is...how many times a day should I take this test and it says that since I have a reg 28 day cycle I should start testing on the eleventh day of MY cycle, but I don't want to take a chance if missing the "right. Time" also, when I do finally get a line that is dark as the control line does that mean I am releasing an egg at that time? Or within the next twelve hrs from that time of the test .? Will someone plz help me out .thank you ,ladies..abd baby dust to all 😄
