Irrational panic?

I took progesterone 7/19-7/23 and clomid 7/28-8/1 and have been inconsistently taking ovulation tests ever since my CD 9 because my Glo chart said my expected fertility window is this Saturday-Next Sunday. All of my ovulation tests have been negative so far, but because I did a clomid ovulation calculator (http://babymed.com/tools/fertility/clomid/) and it said 8/6-8/11 is my expected fertility window, I'm panicking that I haven't had enough sex seeing as we've only BD on 8/6. I realize I still have today and tomorrow, but is everyone different in the sense that there's no real way to calculate that? I've never been on a regular cycle after getting off birth control. Did the clomid not work and I didn't ovulate? Did I miss my window? Is my Glo chart saying the correct dates and that calculator is full of shit? lol I need to chill out, but outside opinions on this would be appreciated!
