When to BD? Is this positive?

Jess
This is my opk from today. CD 19. I took Clomid CD 5-9. First off, is this a positive opk? Secondly, we BD last night. If this is positive, should we BD again tonight? Dr. said every other day. I feel like I don't want to not BD when I might possibly be ovulating today!  Help! 😀
