Positive or no? Update

Ok first time using opk. Bottom two are today 10am and 4pm will check again tonight. Couple questions

1. Is the bottom positive yet?

2. We BD’d last two days should we not BD tonight if it’s not positive?

3. If and when I ever get a positive how many many days should we BD including day of pos opk?

Edit so I guess today is the positive (bottom)??? the left side is control and right is LH (I’m lefty,so I turn them upside down so I can hold the right end)
