How do you check cervical mucus?

Karen
I have been off of birth control for about 6 months. This is our first month on a fertility medicine. I have had 1 on fertility and 1 with out. It's been a long time since I did this. Can someone tell me what day they ovulated on fertility? Believe it or not this is the first time i have ever tracked ovulation. I keep taking ovulation test but the second line is always faint. Any help would be great
