Ovulation Help!

With our first we didn't track anything. We just didn't prevent so I'm totally new to tracking. The 15th I got a positive ovulation strip...at least I think. It's the first picture and it was in morning. The next one I took around 10:30 that night when I got off work. Then yesterday the 16th I took more test and it was still dark. I took one just now and it's the last picture. Picture that has the strip vertical is from the afternoon of the 16th

We baby danced the 13th, 14th, and the morning of the 16th. Do we still need to again? Would it increase chances? Husband doesn't get off until 5 am so it would be when he gets home.
