Ovulation

I've posted on this topic a few times now with very little response so maybe no one has advice but I'll check one more time! 😄 I've recieved positive ovulation tests for 5-6 days straight using FMU. I am using CVS ovulation prediction kit and the instructions say to use FMU. AF not due until 10/14 (adjusted by Glow to 10/10). Hubby and I BD'd on 9/18, 9/19, 9/21, 9/25, 9/27, 9/28. Any ideas why I am still getting positives?
