Help with these results!

Hi Ladies! It is the first month hubby and I are TTC and I decided to start using ovulation strips to pinpoint my ovulation ( my period is irregular). So the last few days, this has been my results. Is this normal to be having a peak this long?? I'm not sure how to read this or determine when I am going to ovulate. My hubby and I baby danced on the 13th, twice on the 14th. How long should we continue to bd? I just want to make sure we are covered 😉
